The article presents investigations of adsorption of heavy metal ions Ni 2+ , Zn 2+ , Cu 2+ by modified zeolites. As a modifier of zeolites of the Holinsky deposit, a sulfur polymer is proposed that is obtained from waste during the production of epichlorohydrin, the main components of which is 1,2,3 - trichloropropane. The mechanisms of adsorption and the results of investigations by the methods of infra-red pectroscopy and energy differential X-ray spectroscopy of the initial samples of materials are described in detail. On the IR- spectres new absorption bands are considered. These bands reflect the nature of fixation of modifier on the surface of sorbent.
