Synthesis and ion-exchange properties of stannic arsenates: separation of Fe3+ from Ni2+, CO2+ Mn2+, and Al3+; separation of Al3+ from Mg2+ and In2+

Abstract
Four chemically different stannic arsenates have been synthesised. Their adsorption behaviour for 20 metal ions has been studied. The high uptake for cations of the exchanger has been compared with other ion-exchange materials produced in our laboratory. Amorphous stannic arsenates are as good as crystalline ones for column operations.
