Sorption of Cadmium by Soils
Abstract
A brief review of the literature on cadmium in the environment, with emphasis on its role in soils and water, is presented. Experimentally, the interaction of cadmium with two soils and one naturally occurring zeolite was examined using calcium-saturated and potassium-saturated samples. The soils preferentially bound cadmium in the presence of either calcium or potassium with decreasing cadmium selectivity as the fractional cadmium surface coverage increased. Cadmium sorption was relatively higher with the potassium soils as compared with the calcium soils. A method for monitoring the flow of cadmium through soil columns was examined.
