Abstract
The sorptive extraction of palladium(II) chloride complexes in the presence of silver(I) chloride complexes from 2 and 4 M aqueous solutions of HCl with a series of Purolite anionites with different functional groups is studied. An anion exchange mechanism of sorption is identified from Raman spectroscopy data. Kinetic properties that are inherent to the investigated ionites and allow the elution of palladium(II) and silver(I) after their extraction in a dynamic mode are revealed.
