Abstract
Abstract Amorphous samples of a new inorganic ion exchanger, lanthanum tungstate, have been prepared under varying conditions. The material prepared by mixing 0.05 M lanthanum nitrate and 0.05-M sodium tungstate in a ratio of 1:2 was studied in detail for its ion-exchange capacity, chemical stability, IR, thermogravimetry, and Kd values. Its columns have been used for the separation of CD2+ from Pd2+, Mn2+, and Cu2+, and Ni2+ from Pd2+.
