The presented research work is devoted to the comparison of the ability of expandable graphite, graphite expanded at 300°C temperature and bentonite clay of Azerbaijani origin to adsorb Na+ ions from NaCl solutions of a known concentration. From the conducted studies, it was found that expanded graphite at 300°C temperature can better adsorb Na+ ions. In addition, the sorption properties of the same adsorbents with respect to Cd2+ ions were confirmed and it was established that bentonite and expandable graphite adsorb Cd2+ ions better.
