Abstract

The paper is devoted to the kinetics of sorption concentration of platinum (II,IV) and rhodium (III) in their simultaneous presence in freshly prepared or stored sulfate-chloride solutions on some macroporous anion exchangers with different chemical structure. It was shown that the process rate is high, although it is slightly reduced in case of stored solutions. The rate of platinum sorption concentration in the presence of rhodium on investigated resins is higher than of rhodium in the presence of platinum. The sorption process was controlled by gel diffusion for all the anion exchangers studied.
