Synthesis and analytical characterization of a chelating resin loaded with dithizone.
A chelating sorbent loaded with dithizone was obtained by chemical reaction with styrene-DVB (5%) copolymer as matrix. The analytical characteristics of the sorbent were established and optimum sorption conditions for Ag, Cu, Cd, Pb, Ni, Co and Zn under static and dynamic conditions determined. The sorbent was applied to determination of copper and lead in river water and of silver in electrolytic copper. After separation of traces of metals on the sorbent and desorption with hydrochloric acid, the metals were determined in the effluent by atomic-absorption spectrophotometry.
