Abstract:
Ash samples were collected from a dumping site (fly ash) and an
electronic precipitator (ESP) of a 640MW thermal power station for
characterization. Analysis of ash sample showed that the major matrix
elements in fly ash were Si and Al together with significant percentage of K,
Fe, Ca, and Mg. Some of the biologically toxic elements Ni, Cr, Pb, B, and
Mo, were also present in substantial amounts. The saturation moisture
percentages of both ashes were higher, but bulk density lower, than the normal
cultivated soils.
