Abstract
Three different types of ion exchangers namely Dowex-50 WX8, AG-2X8 an d Chelex-100 are used to study the sorption behavior of Th(IV) and U(V I)from solutions of Arsenazo-I. The sorption behavior of Arsenazo-I it self is also studied. Possible species sorbed on these resins or prese nt in solutions of U(VI)- and Th(IV)-Arsenazo-I at different concentra tions and at different hydrogen ion concentrations are identified. Fro m the obtained data, optimal conditions for separating the. two elemen ts are recommended. The possibility of individual concentration of Th( IV) and U(VI) as coloured Arsenazo-I complexes on AG-2X8 is evaluated.
