Abstract
Abstract The paper describes the results of a study of the recovery of rhodium (III) from chloride by sorption from strongly and weakly acidic solutions (2 M HCl and pH = 3) by macroreticular anion exchangers on the basis of methylacrylate and divinylsulfide as long-chained cross-linking agent. The initial concentration of Rh (III) in the contacting solution was 0.25–2.15 mmol/L, the process temperature was 20, 30, and 50°C. It was shown that polyfunctional anion exchanger ANS-80 has the best sorption characteristics and can be recommended for quantitative recovery of rhodium (III) at 50°C.
