Abstract
The present article substantiates the theoretical bases of adsorption of heavy metals on modified adsorbents. The aim of this work was to study the simultaneous adsorption of copper and chromium cations on the surface and in the zeolite volume under static conditions. The regularity of the change in the amount of absorbed copper and chromium cations by a zeolite in the initial solution was established. It was settled the chromium ions were better adsorbed on zeolite modified by phosphoric acid. It was established that adsorbents modified in acid conditions were more selective to heavy metals then zeolites modified by NaOH.
