Prediction of KSPfrom RfValues: Thin Layer Chromatography of 47 Metal Ions on Stannic Arsenate in Aqueous Hydrochloric Acid Systems

摘要

The adsorption behaviour of 47 metal ions has been studied in aqueous HCl systems using stannic ersenate layers. The effect of solvent pH on Rfalongwith the complexation effect of HCl has been investigated. On the basis of Rfvalues the KSPof some metel arsenates have been predicted. HCl has been utilized to resolve some binary and ternary mixtures such as Be2+- Mg2+, Zr4+- La3+, Th4+- Ce4+, Th4+- UO2+2, Cr3+- Mo6+or W6+, Sb3+- Bi3+- Cd2+and Ag+- Cu2+- Cd2+.
