Abstract

Surface analytical techniques Including Ion microprobe mass spectrometry and Auger electron spectrometry have been used to demonstrate elemental surface predominance In coal fly ash particles. Substantiation and quantitation of the Ion microprobe data were achieved by using a multitechnique approach Including solvent leaching and bulk multlelemental analysis using spark source mass spectrometry. Elemental surface predominance In coal fly ash Is explained In terms of a volatilization-condensation mechanism. The substantial teachabilities and strongly enhanced surface region concentrations of numerous elements, Including potentially toxic ones such as Pb,TI, Mn, and Cr, Indicate that coal fly ash may have a more deleterious environmental Impact than Is apparent solely on the basis of conventional bulk analysis.
