Abstract  

The uptake of a few polyvalent ions Ca2+ Cu2+, Zn2+, Cd2+, UO2+, Cr3+, Y3+, Ce3+, Nd3+, Sm3+, Tb3+, Tm3+, Yb3+, Lu3+, Zr4+, Hf4+, Sn4+, Nb5+, Se6+, Mo6+ and W6+ at very small concentrations has been studied over ceric tungstate exchanger. A good column variety of the material was prepared by mixing ceric sulphate in 2N H2SO4 and aqueous solution of sodium tungstate in suitable proportion. The ratio of cerium: tungstate was obtained to be 11. Separation of carrier-free95Nb from95Zr and113mIn from113Sn have been carried out by applying a very simple chemical procedure over the column of ceric tungstate. The -spectrum of separated95Nb and113mIn products were found to be of high radionuclidic purity. The separation procedure took less than 15 min and the yields were close to 100%.
