Mineral systems were investigated to determine their effect on copper and zinc removal. This study was in relation to contaminated waters. Isotherms revealed metal removal by kaolinite, montmorillonite, goethite and their mixtures were dependent on particle size, pH, ionic strength, particle concentration and residence time. Kaolinite-montmorillonite and kaolinite-goethite demonstrated different sorption behavior from the single mineral systems. These mineral systems attenuated Cu and Zn removal over the range of pH (i.e. pH 4-8) investigated. Increased ionic strength (i.e.0.00 -0.1 mol/kg) and solid concentration (i.e. 0.002 to 0.01 kg/L), showed a complex response.
