Abstract
The oxygenated functions issued from the oxidative thermal treatment o f mesocarbon microbeads (MCMB) at 320 degrees C were investigated by t hermogravimetric (TG) and Fourier transform infrared spectroscopic (FT -IR) techniques (especially in diffuse reflectance DRIFT mode). Based on the curve-fitted spectra in carbonylfrequencies, the semi-quantitat ive FT-IR analysis gives some evidence on the reactions kinetic and me chanism The direct relation between TGA and FT-IR results is illustrat ed.
