Abstract: | The uptake of Na+, K+, Rb+, Cs+, Ag+, Ca2+, Cu2+, Sr2+, Cd2+, Ba2+, Pb2+, Sc3+, Co3+, Y3+, Sb3+, Tb3+, Zr4+ and Th4+ cations at very small concentrations has been studied over a column of stannic phosphate. The exchanger was prepared by mixing H3PO4, NaCl and SnCl4 in suitable proportions and the ratio of PSn, in the product was obtained to be 1.96. Radiochemical separations of carrier free95Zr from234Th and115mIn, from115Cd have been carried out by adopting a simple chemical procedure over a column of stannic phosphate. The -spectrum analysis showed that the separated products are of high radionuclidic purity. The separation procedures took less than half an hour with quantitative yield. |
