JOURNAL FREE ACCESSA quantitative method by detective current for alkali metal ions during development of ascending paper chromatography is presented. The applied voltage is D.C. 3.0V constant, and the analytical conditions are examined mainly on the following items ;
1) composition of developers, 2) relations between the amount of samples and height of maximum peak current or the product of current-time, 3) influence of counter ions on the determination, 4) separation of ions in the presences of a large excess of Na+ or K+, and 5) precipitating agents for the mixture of Na+ and K+.
The measured deviation in electrometric value is less than 2.6% per μg within 420 μg of Na+ or 525 μg of K+ by this method.View full abstractDownload PDF (737K) -

JOURNAL FREE ACCESSA photometric determination of 0.00010.01% of tellurium in iron and steel with Bismuthiol II was investigated.
The tellurium-Bismuthiol II complex was extracted with chloroform, benzene and carbon tetrachloride from a 0.86N hydrochloric acid, sulfuric acid or perchloric acid solution.
This complex showed an absorption maximum at 335 mμ, and Beer's law obyed up to 50 μg of tellurium when 1 ml of Bismuthiol II solution (0.1%) was used.
The established method was as follows. A half gram of sample was decomposed in 30 ml of sulfuric acid (1+5) and was filtered through a filter paper.
The residue was dissolved in hydrochloric acid and hydrogen peroxide and boiled for 5 minutes. Tellurium was separated by precipitation as metallic tellurium together with arsenic added as a carrier by reducing with stannous chloride.
It was dissolved in nitric acid and perchloric acid and evaporated to vigorous fumes of perchloric acid. After cooling, 5 ml of hydrochloric acid (6N) and 1.0 ml of Bismuthiol II solution were added, and it was shaken for 30 sec. with 10.0 ml of carbon tetrachloride.
The organic layer was washed successively with the washing solution (dissolving 10 g of potassium phosphate, 17 g of sodium borate and 10 g of EDTA in water to make up to 1 litter) and the absorbance was measured at 335 mμ against carbon tetrachloride.
This method was very sensitive and simple, and the time required for an analysis was about 50 minutesView full abstractDownload PDF (974K) -

JOURNAL FREE ACCESSA method has been developed for the determination of microgram quantities of copper, arsenic, and antimony in pure phosphorus by neutron activation analysis. The sample (0.2 g) irradiated for 20 min. in JRR-2 pneumatic tube (neutron flux : 8×1013 n/cm2·sec.) was dissolved with nitric acid after addition of 10 mg each of copper, arsenic, and antimony as the carriers. The three elements were removed from phosphorus as sulfides and separated mutually by anion exchange chromatography. Radioactivities were measured by a gas-follow counter and a γ-ray spectrometer. The mean chemical yields were 86% for copper, 85% for arsenic and 79% for antimony. As little as 7×10-4 μg of copper, 5×10-4 μg of arsenic and 9×10-4 μg of antimony could be determined.View full abstractDownload PDF (754K) -

JOURNAL FREE ACCESSA coulometric study was made on the possible existence of deviation in carbon values of commercial standard samples of iron and steels.
A standard sample preliminarily selected (A) was at first analysed for calibrating the apparatus against the certified value of this standard and, successively, the value XA for the common reference sample X was obtained. The apparatus was then recalibrated against another standard sample (B) and the value XB was obtained for the above reference X. By repeating this procedure, the analyses were done for a number of stainless steels (A……D), carbon steel and low alloy steels (a……d), and the corresponding values for the common reference (XA……XD) and (xa……xd) were subjected to variance analysis to know whether there was any significant difference between them.
The result indicated an existence of statistical variance among certified carbon value of those standard samples, especially between carbon values of NBS stainless steel and BCS stainless steel.View full abstractDownload PDF (604K) -

JOURNAL FREE ACCESSTantalum and niobium in heat resistant alloys were precipitated quantitatively by tetraphenylarsonium chloride (TPAC) from, respectively, >1M and >8M hydrofluoric acid solution, and were readily separated from tungsten, molybdenum, titanium and zirconium.
A sample was taken in a polyethylene beaker, and decomposed by heating on a boiling water bath with 30 ml of hydrofluoric acid and 40 ml of aqua regia. The solution was then made up to 130 ml with 30ml of hydrofluoric acid and water. Twenty milliliters of TPAC solution (0.025M) was added, and the mixture was allowed to stand for 30 min. in the water bath drawn from fire. The aged precipitate was filtered with a bit of paper pulp through a filter paper and washed with TPAC washing solution (10 ml of TPAC solution and 1 l of 1M hydrofluoric acid). It was then transferred to a high purity alumina crucible, ignited at 900°C for an hour and weighed as combined pentoxides. If necessary, the oxides were fused to dissolve for respective determinations of Nb and Ta by spectrophotometry. The mutual separation of niobium and tantalum was not possible by this procedure.View full abstractDownload PDF (639K) -

JOURNAL FREE ACCESSAlthough we have many theories of programmed temperature gas chromatography (PTGC), there is not anything that the characteristic value of PTGC is related directly to the corresponding value of isothermal gas chromatography (IGC).
The author studied those characteristic values by using gas chromatography with mass flow controller and subsequently found a linear relation between relative retention time of PTGC and logarithmic relative retention time of IGC. And the initial and programming temperatures which were significant factors in PTGC were discussed to take a good linearity.
The linear relation held not only within homologs but also between different homologous series. The linearity was confirmed with many perfume compounds.View full abstractDownload PDF (739K) -

JOURNAL FREE ACCESSExtraction-spectrophotometric determination of molybdenum(VI) has been investigated by using extraction of molybdenum complex of Pyrocatechol Violet with quaternary ammonium salt.
Molybdenum complex of Pyrocatechol Violet is extracted into various organic solvents in the presence of dialkyl-methylbenzylammonium chloride, but the composition of the complex extracted into organic solvent depends on ligand concentration and pH of aqueous phase. The complex extracted into chloroform from 0.250.6M hydrogen chloride solution has an absorption maximum at 560 mμ, the molar ratio of molybdenum to Pyrocatechol Violet being 1 to 2. Under optimum conditions, Beer's law is obeyed at least up to 10×10-6M molybdenum in chloroform. Tin(IV) and tungsten(VI) interfere with the determination. Zirconium(IV) forms a complex with Pyrocatechol Violet but is not extracted.
The extraction with quaternary ammonium salthas an effect to liberate hydrogen ion associated to carbonyl group on Pyrocatechol Violet in an acidic medium.View full abstractDownload PDF (1101K) -

JOURNAL FREE ACCESSThe present investigation has aimed at establishing a practical determination method of mercury in brine purification mud.
The addition of iron powder as a reducing agent was effective to obtain the quantitative recovery of mercury from mercuric oxide at a temperature as low as 100°C. Futhermore, by covering sample with zinc powder, both mercurous and mercuric chlorides were decomposed completely without sublimation. Silica gel for chromatographic use was most effective for the prevention of the interfering deposition on the gold foil. The formation of amalgam was quantitative by heating at 600°C (measured at the bottom of crucible) for 30 min.
The recovery tests and the analyses of mud samples gave accurate results.View full abstractDownload PDF (759K) -

JOURNAL FREE ACCESSIn differential thermal conductivity cell, which measures concentration of selective component in a multi-component system, perfect equality of dynamic properties between sensing side and reference side of the given katharometer is essentially required. The authors previously reported a theoretical analysis on the above cell balance and a practical method for counterbalancing. The bridge, counterbalanced by the cell balancing helicalohm as illustrated in Fig. 3, was practically non-sensitive with a change of thermal conductivity of the carrier gas.
Further approaches for better operating conditions have been made by investigations changing the flow rate of the carrier gas and the katharometer temperature. Change of the output signal due to a unit change of the flow rate was approximetry 0.1 mm/(ml/min), 0.04 mV/(ml/min), at a cell current of 100 mA. This value was constant with all of the flow through type, semi diffusion type and diffusion type katharometers when the same pair of the filaments had been mounted. Estimated sensitivity with 2% CO2 in helium under varied flow rate of the carrier gas was also constant at the three different types of katharometers, and hence it was obvious that the sensitivity was mostly attributable to the characteristics of the katharometer filaments. Fluctuation of the output signal due to the change of katharometer temperature could be zeroed by positioning the central point of the cell balancer in the bridge circuit. This balancing point, however, did not normally coincide with the position previously reported for the heat conductivity of the carrier gas.View full abstractDownload PDF (1008K) -

JOURNAL FREE ACCESSPhotometric reading of the conventional spectrophotometer is generally done by a scale calibrated linear in transmittancy : T. We constructed a spectrophotometer having a linear scale in absorbancy : A, and compared its reading error, error by zero setting, error by full scale setting and error with absorbancy scale change with those of usual photometer with transmittancy-linear scale.
Relative errors by an absorbancy-linear spectrophotometer were found to be represented as functions of absorbancy : A, that is, the reading error 1/A, the error by zero setting also 1/A, the error by full scale setting (1-A)/A and the reading error by a change of absorbancy scale 1/(A+A1).
This indicated that each error function would decrease in accordance with an increase of absorbancy : A, which was confirmed by the experimental results.View full abstractDownload PDF (1173K) -

JOURNAL FREE ACCESSThin-layer chromatographic behavior of 47 metal ions on DEAE has been investigated in 12 different solvents. In methanol-nitric acid media Rf values are given as a function of nitric acid concentration at a fixed solvent volume ratio (methanol-nitric acid, 20 : 1, v/v). Many separations of metals are possible by proper selection of the concentration of nitric acid. In other systems (organic solvent-8M nitric acid, 20 : 1, v/v) only a few metals advance upwards and many others remain at the start, so that these systems are useful for the separations of particular metal ions. Thus, iso-propanol is specific for Se(IV) and Re(VII), n-butanol and iso-butanol for Au and Se(IV), aceton and ethyl acetate for Au and Sb(III), dioxan for Sb(III), ethyl ether for Au, acetic acid for Fe(III) and Ge, and tetrahydrofuran for V(IV) and Au.
Difference in Rf values on DEAE and a plain crystalline cellulose Avicel in several solvents suggests the presence of ion exchange adsorption by a weakly basic anion exchanger DEAE even in methanol-nitric acid medium.View full abstractDownload PDF (1019K) -

JOURNAL FREE ACCESSA phase diagram of hexamethylbenzene-picryl chloride system was made up by micro DTA, in which a mixture of suitable mole-ratio was put in an air-tight cell in order to prevent its sublimation. The measuring conditions were : sample size about 3 mg and heating rate 5°C/min. The obtained diagram was more precise than that by macro DTA because of high resolving power of micro DTA.
The authors further proposed the measurement of boiling points of alkyl-benzenes as a new application of micro DTA, whereby the vaporization of samples was restricted by a pin hole on the air-tight cell.
The boiling points of ο-xylene, m-xylene, p-xylene, toluene and benzene were determined successfully under the measuring conditions : sample size 5 μl, heating rate 10°C/min and pin hole diameter 0.1 mm.View full abstractDownload PDF (762K) -

JOURNAL FREE ACCESSThe extraction process of 8-quinolinol from CCl4 phase into aqueous HCl solution is investigated, and diffusion constant of 8-quinolinolium ion (H2Ox+) is determined by means of the diagonal schlieren method.
The lower half of the inner wall of a diffusion cell was treated with silicone oil to keep a sharp and stable interface between the aqueous and organic phases. To it was added by a syringe 0.3M 8-quinolinol solution in CCl4 just to the siliconized level, and then an aqueous 0.3N HCl solution was poured carefully thereon. Assuming this time of addition to t=0, the schlieren pattern was recorded on the photograph at the appropriate time intervals and the diffusion constant was calculated according to equations (1)(3).
The diffusion constant obtained for H2Ox+ ion in aqueous HCl solution was 4.37×10-6 cm2·sec-1 for 0.3N HCl at 18.5°C, and 0.325×10-6 cm2·sec-1 for 1.0N HCl at 16.5°C.View full abstractDownload PDF (467K) -

JOURNAL FREE ACCESSA method of chromatographic separation of aminobenzoic acid isomers, in which a sulfonated cation exchange resin Amberlite CG-120, Cu(II) form, was used as a stationary phase and aqueous ammonia as a developer, was investigated.
Studies on the adsorption of the three isomers to the resin in aqueous ammonia showed that (a) the Kd value of each isomer decreased with increasing concentration of ammonia, (b) the Kd value of ο-isomer was much larger than that of m- or p-isomer at a pH range from 8.0 to 10.0 because of the formation of a stable complex and (c) the rate of adsorption and desorption of m-isomer was different from that of ο- or p-isomer probably because of the difference in composition of the complex.
The separation of ο- and m-isomers or of ο- and p-isomers was successfully achieved when a mixture was eluted through a column of φ 14 mm×390 mm with aqueous ammonia of pH 8.4 at a flow rate of 0.3 ml/min., but m- and p-isomers could not be separated except when pure water was used as a developer.
From the studies on the stability of Cu-ο-aminobenzoic acid complex in NaOH solution of pH 10.0, it was found that NaOH solution also was useful as a developer for separating ο- and m- or ο- and p-isomers.View full abstractDownload PDF (1215K) -

JOURNAL FREE ACCESSA simple and rapid titrimetric method was proposed for the determination of 0.010.3% of aluminum in zinc base alloy. For the separation of aluminum from large amounts of zinc and other metals, the benzoate precipitation method was applied, first in the presence of a large amount of ammonium acetate and then in the presence of thioglycollic acid.
Optimum amounts of ammonium acetate, benzoate and thioglycollic acid were decided. The amount of iron which was precipitated with aluminum benzoate had no effect on the recovery of aluminum in the reprecipitation step.
The proposed method was applied to the analysis of synthetic sample and secondary zinc base alloys. Aluminum recovery of more than 95% was obtained with several percent of relative error. A single determination could be done within 45 hrs.View full abstractDownload PDF (476K) -

JOURNAL FREE ACCESSIt has been related hitherto that trivalent chromium reacts very slowly with EDTA and sexivalent chromium does not react with it.
The authors have found that, if trivalent chromium is newly prepared by reducing sexivalent chromium with a suitable reducing agent, it reacts rapidly with EDTA and subsequently forms Cr(III)-EDTA complex which shows absorption peaks at 395 mμ and 550 mμ. Consequently, reducing agents such as ascorbic acid, hydroquinone, sulfite and thiosulfate can be determined indirectly by measuring absorbance at 555mμ.
It is considered that the very slow reaction of Cr3+ with polyaminocarboxylic acids may be due to the slow rate of exchange reaction of water molecules coordinated to chromium ion, which makes it reasonable that the newly reduced trivalent chromium ion reacts rapidly with EDTA.View full abstractDownload PDF (255K) -
