The possibility of using sand, silicagel and zeolite-containing rock (ZCR) for sorption of benzene and bacteria Escherichia Coli in water environment was investigated. It was established that ZCR and silicagel show insignificant sorption activity to benzene, but high – to E.Coli. The additional contribution to benzene sorption on ZCR was brought by the sorption centers in the interlaminar space of smektites. Sorption of E.Coli and benzene is essentially determined by the size of specific surface of a sorbent. ZCR and silicagel can be recommended for further tests concerning clean-up of polluted water environments as sorbents of pathogenic and conditionally pathogenic microorganisms.
