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