The use of NaX zeolite, in the sorption of cobalt and cadmium from aqueous solutions has been investigated. Ion exchange experiments were performed with cobalt and cadmium solutions at various pH and concentration. The cobalt, cadmium and sodium content were determined by neutron activation analysis. It was stated that the selectivity for cadmium is higher than for cobalt.
