Abstract

A method has been optimised to preconcentrate uranium from waters using the ion exchanger Hyphan. To make Hyphan selective for uranium, other transition metals are masked with EDTA which only forms weak complexes with uranyl ions. Three different sets of experiments are described. The first set is aimed at the optimisation of the method itself; with respect to a group of parameters, the experiments are all carried out with a standard solution of uranium in bicarbonate. In the second set, the optimised method is applied to solutions with decreasing concentrations of uranium. In the third set, natural waters are used instead of bicarbonate solution.
