REMOVAL OF COPPER AND ZINC FROM AUTOMOTIVE WASTEWATER BY PUROLITE C-104 ION EXCHANGE RESIN

摘要

In this study, removal of copper and zinc in wastewa-ter was studied by using Purolite C-104. The removal efficiencies as a function of initial heavy metal concentrations, contact time, and resin dosage were investigated over experimental periods lasting 30 to 180 min. Adsorption isotherms were calculated according to the linear form of the Langmuir and Freundlich isotherms. The result showed that the Freundlich adsorption capacities of Zn~(+2) and Cu~2 on Purolite C-104 were calculated as 2.96 mg g~(-1) and 1.803 mg g~(-1). Langmuir adsorption capacities for Zn~(+2) and Cu+~2 were calculated as 7.92 and 1.218 for Purolite C-104. The experimental data were well fitted to the Langmuir isotherm model with a reasonable R~2 value.
