Abstract :
A technique, utilizing emission spectroscopy, developed at Tennessee Tech (USA) to detect trace metals in thermal power plant coal ash has recently been extended to analyze coal prior to burning. Seven elements are of particular interest: arsenic; cadmium; lead; mercury; thallium; antimony; and selenium. The analysis of coal, as well as the corresponding coal ash, has been performed to develop a correlation between spectral intensities. This may lead to the prediction of toxic trace metal levels before a particular batch of coal is burned in a thermal power plant
