JOURNAL FREE ACCESSExtracting free sulfur in vulcanizates with benzene and removing MBT by shaking with an aqueous alkaline solution, one can determine a.c.-polarographically the free sulfur in a small amount with the electrolyte-solvent mixture composed of benzene, methanol, pyridine and concentrated hydrochloric acid.View full abstractDownload PDF (339K) -

JOURNAL FREE ACCESSThe polarographic determination of lignosulfonate in sulfite spent liquor was investigated. Though the lignosulfonate itself does not show any d.c. polarogram, it combines quantitatively with polarographically active methyene blue resulting in the precipitation, and methylene blue was used as the indicating Snbstance of lignosulfonate in sulfite spent liquor. Consequently, it was found that lignosulfonate was determined without the disturban-ce from the impurities in sulfite spent liquor. Moreover, it was found that the accurate and rapid determination of lignosulfonate was carried out easily with the am.perometric titration of methylene blue by sufite spent liquor.View full abstractDownload PDF (411K) -

JOURNAL FREE ACCESSThe direct current polarography of the inert chromium(lll) Eriochrome Violet B complex has been investigated in both acetic acid and ammonia buffers. The three reduction waves obtained in ammonia buffer have been interpreted with the aid of Kalousek polarograms as resulting from the consecutive reductions of (1) the dye ligand, (2) the chromium(lll) species to a chromium(ll) species, and (3) the chromium(ll) species to chromium metal. One of us (G.H.A.) wishes to express his gratitude to the Japan Society for the Pro-motion of Science for the granting of a research fellowship.View full abstractDownload PDF (633K) -
