Adsorption behavior of metal ions by amidoxime chelating resin

Rivas BL; Maturana, HA; Villegas, S

Abstract

The adsorption properties of poly(acrylamidoxime) chelating resin for Cu(II), Cd(II), Hg(II), Zn(II), Pb(II), Cr(III), and U(VI) are investigated by the batch technique. Based on the research results of the binding capacity effect of the pH value on sorption kinetic experiments, it is shown that this resin has higher binding capacity to uranyl ions, fast kinetics, and very good selectivity from binary metal ion mixtures with Cu(II) and Pb(II). The uranyl ion sorption strongly depends on the pH value of the solution. The highest value of 99% is at pH 5, but at pH 1 there is no retention. The adsorbed UO(2)(2+) can be eluted by sulfuric acid and sodium carbonate. (C) 2000 John Wiley & Sons, Inc.
