Abstract

This paper reports the demineralization of sub-bituminous coal with ethylenediamine tetraacetic acid (EDTA), HCl, HF, chloroform and acid mixture. The residual coal from each treatment was analyzed using Fourier Transform Infrared (FTIR) spectroscopy and Ultimate analysis. FTIR spectrum of raw coal sample was recorded for enhancing the comparison. The spectrums were found to have similar broad characteristics. It was evident from the results that amongst the leachants used, Hydrofluoric acid and acid mixtures had significant effect in removing the mineral matter and oxygenated functional groups.
