Separation and determination of sulfide sulfur and sulfate sulfur in soda lime silicate glass

The quantities of sulfide sulfur and sulfate sulfur and the average valence of sulfur in soda lime silicate glass are important because they affect the number of bubble defects and color of the glass. In this paper, we describe and demonstrate a new determination method of sulfide and sulfate in glass. This method consists of decomposition of a glass material and the separation and determination of sulfide and sulfate. Hydrochloric acid and hydrofluoric acid decompose the material in a vessel. The vessel is combined with a series of traps. Hydrogen peroxide and sodium hydroxide in the traps absorb hydrogen sulfide that volatilizes during decomposition. This method allows for the determination of sulfate remaining in the vessel and the trapped sulfide, respectively. The method is tested on two glass reference materials with commonly accepted testing equipment. The sums of sulfide and sulfate are within the range of each certified value. The average valences of sulfur, which are calculated from the quantities of sulfide and sulfate, are in good agreement with the average valences of sulfur obtained by wavelength-dispersive X-ray fluorescence spectrometric analysis.

Rapid determination of sulfide sulfur in anaerobic system by gas-phase molecular absorption spectrometry

A detection system was designed for rapid and accurate determination of sulfide sulfur in an anaerobic system by gas-phase molecular absorption spectrometry (GPMAS).

Chemical Analysis of Soda‐Lime‐Silica Glasses for Trace Quantities of Several Colorants

Methods for the analysis of soda‐lime‐silica glasses for trace amounts of CrzO3, COO, NiO, CuO, and selenium are described; the determination of sulfide sulfur in amber glass bottles is also described. The applicable range of these methods is as follows: for Cr2O3, 2 to 600 pgm.; for COO, 2 to 20 pgm.; for NiO, 5 to 100 pgm.; for CuO, 5 to 80 pgrn.; for selenium, 5 pgm. (approximate minimum); for sulfide sulfur, 0.005 to 0.10%.
