Summary

A reproducible and chemically stable inorganic ion-exchanger, niobium arsenate has been prepared by mixing acidic solutions of niobium sulphate and sodium aresenate in the ratio 1∶4 under different conditions. Its exchange behaviour after heat treatment has been studied. The analytical utility of this material is illustrated by its ability to separate quantitatively Ni(II) from V(V) and Fe(III). Mn(II) from V(V) and Fe(III).
