Application of x-ray fluorescence spectroscopy (XRF) to analysis of 7 coals and to SRC (solvent refined coal) from five of them showed that XRF allows simultaneous analysis of 17 elements, i.e., Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, and Sr, in only 45 minutes. Comparison on three standard samples of XRF with atomic absorption spectroscopy for analysis of iron and with a standard Leco sulfur analyzer showed best accuracy with XRF. A linear correlation was observed between the total contents of all these elements other than sulfur and phosphorus and the ash content. The contents of all elements were much lower in SRC than in coal, with the greatest differences for Si, S, K, Ca, Ti, Cr, Fe, and Sr.
