Synthesized composite sorbents KU2×8 - Fe(OH) 3, KU2×8 -Sn(OH) 2, KU2×8-CuS, KU2×8-ZnS, KU2×8-PbS on strongly acidic cation matrix of KU2×8. Conducted study of sorption kinetics of copper (II), zinc and cadmium from solutions of their 0.01n. salts. Worked out a mathematical model of copper sorption by composite sorbents. An explanation of heavy non-ferrous metals sorption process on the composite sorbents with hydroxide and sulfide active component accordingly was suggested based on mechanism of coordination copolymerization.
