The sorption behavior of cobalt and cadmium by zeolite Y has been inve
stigated. Cobalt and cadmium solutions were exchanged with the zeolite
at different pH's. Cobalt, cadmium and sodium in the samples were det
ermined by neutron activation analysis. The sorption of cadmium was hi
gher than that of cobalt, however, the selectivity for both cations by
the zeolite was low.
