“…6 coals have also concluded that they are relatively rich in aliphatic, sulfidic organic compounds (5,6,7). However, lt is pertinent that the mass spectroscopic work on this coal has not provided evidence for aliphatic sulfur compounds (8,9,10 (11,12,13). The product, which was recovered after acid hydrolysis, had less than 0.1% iron, and there were no pyrite reflections in the powder diffraction X-ray spectrum (13).…”

An X-ray fluorescence method is described for the direct determination, without pretreatment, of up to 55 trace elements in coal and coal-derived materials. A single assay specimen is prepared by blending finely crushed sample with a binder and briquetting. Calibration is effected by a suite of synthetic calibration standards prepared from spectrographically pure materials blended into graphite. Variations in ash and sulphur content required matrix absorption corrections to analyte and background intensities, which were achieved by use of relationships with the measured Compton scattered radiation. Prior knowledge of or assumptions concerning the composition of the coal are not required. Accurate results are presented for three NBS coal standard reference materials. Certain elements (including T1, Hg, Te, In, Cd, Ag and most rare earths) are normally present in coal at levels below the detection capability of the described method and require quantification by alternative techniques. 0 Heyden
