Abstract
The sorption of palladium(II) microquantities from a chloride and chloride-nitrate (V) model 0.1–6.0 M HCl, 0.1–0.9 M HCl-0.9-0.1 M HNO 3, 1.0 M ZnCl 2-0.1 M HCl and 1.0 M AlCl 3-0.1 M HCl systems on strongly basic polyacrylate anion exchangers was studied. The research was carried out by means of dynamic and static methods. The recovery factors of Pd(II) were determined from the static studies. The working ion-exchange capacities as well as weight and bed distribution coefficients of Pd(II) were calculated from the breakthrough curves. The commercial strongly basic anion exchangers of the functional quaternary ammonium groups — Purolite A-850 and Amberlite IRA-958 — can be used in recovery technologies of Pd(II) from anodic slime, wastewaters and spent catalysts due to their high selectivity.
