Abstract
Radioactive elements may be retained by clays. The ability of natural Mexican clays to retain radioactive Co from aqueous solutions, discuss ed. Experiments were performed with solutions containing labeled cobal t. The effect of contact time on Co2+ retention was studied. It was fo und that the Co2+ uptake value in dehydrated montmorillonites is betwe en 0.30 and 0.70 mes g(-1) of clay. A sorption sequence was obtained f or the various clays. The samples were characterized, before and after cobalt exchange, by X-ray diffraction.
