Paper Abstract

Diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) was used to qualitatively identify organic impurities in sulfur. The impurities were furthur graded by sorbing carbon disulfide (CS2), and measuring the area under the band from 1600 to 1500 cm-1 relative to the sulfur band at 1300 cm-1, as observed in the DRIFT spectrum. The sorption of CS2 was proportional to the amount of organic impurity, was not removed by vacuum at 70 C, and was reproducible whether sorption was by infusion or by exposure to vapor.
