Abstract
AbstractSummary: Resins containing sulfonic acid groups by radical polymerization were synthesized. The metal ion retention properties were studied by batch and column methods for the polluting metal ions Cd(II), Pb(II), and Hg(II).pH exercises an important effect on the retention: the metal ion sorption increases with increases in the pH. The maximum retention capacity was determined after three contacts at optimum pH. Resin R1 obtained the highest value 1.207 mmol/g resin for Cd(II). Different eluent reagents were used to recover the resin. Resin R1 loaded with Pb(II) was completely recovered using 4 M HCl as stripping reagent.
