The Quantitative Determination of Elemental Sulfur Dissolved in NM by Laser Raman Spectroscopy.
Abstract
Laser Raman spectroscopy has been successfully applied to the quantitative determination of free sulfur dissolved in samples of methyl polysulfide (NM). The Raman method consists of weighing out the NM and carbon disulfide and determining the intensity ratio of the 221 cm-1 sulfur band and the carbon disulfide band at 800 cm-1. After consulting a calibration curve of percent (w/w) sulfur in carbon disulfide, the weight of sulfur present in the carbon disulfide is determined and the percent sulfur in the NM is calculated. The Raman method gives good results (standard deviation of 0.1%) which are comparable to those obtained by thin-layer chromatography (TLC). The Raman method, being composed of fewer steps than the TLC method, is a simpler and more rapid technique. (Author)
