Sorption properties of a new composite sorbent containing Black Sea bottom sediments and oxidized carbon produced from a natural raw material, coconuts were examined. Quantitative characteristics demonstrating the selectivity of sorption of Cu 2+ , Zn 2+ , and Cd 2+ ions by the synthesized sorbent and its components were obtained. The role played by the sorbent components in the sorption processes under study was elucidated.
