ADSORPTION OF TRACE ELEMENTS FROM SEAWATER BY CHELEX 100

Abstract

Chelex 100 was evaluated as an ion-exchange resin for the extraction of trace elements from seawater. A modification of the limited bath technique was used, in which resin was added to a solution containing the trace element. After time for equilibration, the solution was analyzed and the fraction of the activity adsorbed by the resin was determined. Chelex 100 appears to be an excellent ion-exchanger for extracting a number of trace elements from seawater. These include: Ni, Zn, Ce, La, Tm, Pb, Am, Tb, Mn, Bi, Pu, Cr, Th, Co, Cd, Fe, and Hg.
