Investigating the factors which influence upon the colorimetric determination of trace quantities of boron with carmic acid by reference to Standerd Methods and W. C. Smith's method, we established an improved method for colorimetric determination of them with carmic acid reagent. By this method the recoveries of boron in samples not containing organic matter and in samples of biological materials were 99.70±0.23%, 98.50±0.75% respectively.

Separation and Determination of Saccharin, Dulcin, and Cyclohexanesulfamic Acid Yasushi Mihashi and Fumiko Kobayashi

The mixtures of saccharin, dulcin, and cyclohexanesulfamic acid are separated by extraction with ethyl acetate and with ether. Saccharin is precipitated, as the silver salt and the precipitate is dissolved in warm diluted nitric acid and the solution is titrated with ammonium thiocyanate. Dulcin is determined colorimetically, utilizing p-dimethylaminobenzaldehyde. Cyclohexanesulfamic acid is deaminated by nitrous acid. The resulting sulfate ion is titrated using barium ion and a standard disodium dihydrogen ethylenediamine tetraacetic acid solution. The proposed method is convenient for routine work.

Determination of Kjeldahl Nitrogen in Foodstuffs as Indophenol

Yasushi Mihashi, Saiko Fukuchi

1963 Volume 9 Issue 1 Pages 29-31

Show abstractHide abstract

The indophenol method for determining Kjeldahl nitrogen has been studied and has been applied to the analysis of foodstuffs. A photometric determination of ammonia is based on the reaction with phenol and hypochlorite, to give an indophenol which is intensively blue in an alkaline medium. The procedure is better in reproducibility than previously reported methods. The indophenol method may be considered a general method for the determination of Kjeldahl Nitorogen in foodstuffs. The results obtained from the analysis of certain foodstuffs and organic compounds by the indophenol method are compared with those obtained by the semimicro-Kjeldahl method.
