The Determination of Sulfur and Its Compounds in Rayon1

Abstract

The determination of sulfur and its compounds in rayon is described. These sulfur compounds are sulfides, sulfites, xanthates, and sulfates. The methods for the determina tion of these compounds and elemental sulfur were first applied to standard solutions of these compounds. After it was established that these methods yielded accurate results, they were applied to the determinations in rayon. Apart from these determinations, the sums of some and of all compounds were determined. These determined sums proved to be in good agreement with those calculated from the determinations of the individual amounts, so that it is assumed that all methods yield accurate results when applied to the determinations of the S-compounds in rayon.
