Abstract
The adsorption behavior of 52 metal ions has been studied in DMSO-HCI systems using stannic arsenate layers. A remarkable feature of this study is a dramatic decrease in adsorption of many ions when compared to the corresponding water-HCI systems. This specific DMSO effect has been explained and used for important binary and ternary separations. In DMSO-5 M HCI (1:1), Zr4 + and Mo6 + have been separated from each other and from a mixture of Th4 +, Ca2 +, Y3 +, Nb5 +, Ta5 +, In3 +, Ti4 +, and the rare earths.Keywords
