✦ Synopsis

Fly ash samples collected by means of an electrostatic precipitator from the coal-Ðred 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 Ñuorescence (EDXRF) techniques. Sixteen elements, namely K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Rb, Sr, Y and Pb, were quantiÐed using both PIXE and EDXRF. These concentration values can be helpful in developing a pollution abatement approach for various applications of Ñy ash such as cement manufacture and ceramics, and as a source of major and micro-nutrient elements for healthy plant growth.
