Abstract

"The sorption and desorption of lead and zinc on soil samples from the "New Lead Belt" of southeastern Missouri and from Springfield, Missouri, were investigated using both column and batch systems. These cations were selected for study because of the possible effects which soil pollution in the "New Lead Belt" mining region could have on shallow aquifers and because both metals are utilized in the electroplating industry.

It was found that soil has the ability to sorb lead and zinc; however, the cation-exchange capacity (C.E.C.) of the soils studied was not fully satisfied, though there was evidence that i f cations were applied over a period of time, the total soil C.E.C. might have been approached. Lead was sorbed perferentially when compared with zinc. The amounts of these metals which were sorbed depended on the soil layer and characteristics, particularly C.E.C. and organic content; therefore, prior to the disposal of metallic wastes on soils, laboratory and/or field studies should be conducted to determine the sorption capacity of the soils for the particular cations to be disposed.

Residual windblown minerals from the only lead smelter in the "New Lead Belt" could not be leached from the soil using re-distilled water to simulate rainfall. Lead and zinc sorbed from acetate and fluoborite solutions were partially removed from the soil with re-distilled water; however, a solution containing humic materials increased their removal rate"-- Abstract, pp. ii-iii
