Abstract

The solvents tributylphosphate (TBP) and odourless kerosene (OK) are widely used to extract plutonium(IV) and uranium(V) in nuclear processing plants. Their use depends upon their relatively low affinity for fission products, but small amounts of radioisotopes are taken up by them. To aid disposal/reuse of these solvents it is of use to study ways of removing radioisotopes of Cs and Sr from them. This paper describes simple distribution coefficient (K d ) measurements to test the ability of aluminosilicate zeolites to remove137Cs and90Sr/90Y from TBP, OK and their mixtures.
