Abstract
PURPOSE:To separate niobium and tantalum with high accuracy by bringing the mixed soln. contg. one or more kinds among HF, NH4, K and H2SO4 and in which one or more kinds of metallic ions as well as Nb and Ta coexist into contact with a specific solid extractant which is insoluble in water. CONSTITUTION:HF contg. soln. or the water soln. contg. HF and H2 SO4 in which one or more kinds of metallic impurities such as Fe, Mn, Ti, etc., as well as Nb and Ta coexist is used. The adsorbent in which the extractant selected from the group of O contg. organic solvents and alkyl amine group is soldified or crosslinked into a porous carrier is brought into contact with said water soln. By this method, Ta in said water soln. is selectively adsorbed. In this case, the above-mentioned solid adsorbent does not melt into the water soln. at all. Said metallic ions such as Fe, Mn, etc., have less adsorbent distribution ratio than NbOF ions, by which Ta and Nb are perfectly separatable. Said adsorbent can be regenerated by bringing the water soln. contg. NH4 and HF or K and HF into contact therewith.
