Fly ash samples collected by means of an electrostatic precipitator from the coal‐fired thermal power plant of the National Thermal Power Corporation located at Talcher in India were characterized using particle‐induced x‐ray emission (PIXE) and energy‐dispersive x‐ray fluorescence (EDXRF) techniques. Sixteen elements, namely K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Rb, Sr, Y and Pb, were quantified using both PIXE and EDXRF. These concentration values can be helpful in developing a pollution abatement approach for various applications of fly ash such as cement manufacture and ceramics, and as a source of major and micro‐nutrient elements for healthy plant growth. © 1997 by John Wiley & Sons, Ltd.
