Abstract  

Separations of tracer cations in parent daughter systems such as carrier-free210Bi from210Pb,90Y from90Sr and UX1 from U have been carried out in a column of ceric phosphate as ion exchanger. The exchanger has been prepared by mixing ceric sulfate in hot 10M orthophosphoric acid at 80°C and keeping for overnight. A pale yellow coloured precipitate was formed which was washed, dried at 70°C for 48 hours when a hard, granular variety suitable for column use, with a cerium to phosphate ratio of 1∶2 was obtained. 0.1M H3PO4 was used as medium in each of the systems studied. The β-decay curves of the separated210Bi and90Y and the γ-spectrum of UX1 show that all these activities are radiochemically pure. The separation procedures adopted in each case were very clean and simple, gave quantitative yields and took less than half an hour.
