Abstract

X-ray fluorescence method using Compton scattering for the determination of ash in coal has been systematically studied for application to Indian Coal. Fluorescent intensities from major constituents such as Al2O3, SiO2, TiO2, Fe2O3, CaO and their various combinations were used in conjunction with the reciprocal of the Cr Kα Compton intensity in a regression equation. Varying degrees of correlations were obtained between the values of ash determined by conventional methods and those calculated from X-ray data. It is found that Ti fluorescent intensity plays a major role in the regression equation and its contribution cannot be ignored if the Cr X-ray tube is used.
