Paper Abstract

The advantages of Thermal Gravimetric Analysis/Fourier Transform Infrared Spectroscopy (TGA/FT-IR) for material characterization has been successfully demonstrated by the analytical chemist. This hyphenated technique has generally been utilized for assigning evolved gases to the detected weight losses of the material as it is being heated. In this study, the FT-IR is used to monitor the reaction products which evolve from pyrite as it is slowly heated from room temperature to 600 degree(s)C under air. The spontaneous and cyclic releases of sulfur dioxide are monitored during the experiments by high resolution Evolved Gas Analysis.
