A new inorganic ion-exchanger, tantalum arsenate, has been prepared under varying conditions. The exchanger prepared by mixing 0.1 M tantalum pentoxide and 0.1 M sodium arsenate in the ratio of 1:4 at pH 0 has been studied in detail for its ion-exchange capacity, pH titrations, and K d values. The material can be prepared reproducibly. Its analytical importance has been established by the following quantitative separations: Zr 4+ from Tm 3+ , Zr 4+ from Eu 3+ , Pr 3+ from Eu 3+ , and Pr 3+ from Tm 3+ .
