This work examines the adsorptivity of different combinations of lead, copper and cadmium ions onto the clay mineral kaolinite covering a wide range of concentrations of single, binary and ternary solutions. Batch adsorption equilibrium tests were used. The results of single Pb^<2+>, Cu^<2+> and Cd^<2+> solutions were compared with those of binary Pb^<2+>Cu^<2+>, Pb^<2+>Cd^<2+>, Cu^<2+>Cd^<2+> and ternary Pb^<2+>Cu^<2+>Cd^<2+> solutions. Results indicate that the adsorptivity of heavy metal ions is slightly lower in binary and ternary solutions than for single ion species in the solution. Lead shows a higher selectivity on kaolinite of the three heavy metal ions, while Cu^<2+> and Cd^<2+> give very similar selectivities.
