Abstract
The sorption isotherm and kinetic of Cu2+, Pb2+, Zn2+ , and Cd2+ ions onto sewage irrigated soil (El-Gebal El Aasfar-Qalubia) was examined as a function of the retention time and initial ion concentration using batch equilibrium sorption experiments. Results show that the Cu, Pb, Zn and Cd metal ions onto the soil is relatively rapid and sorption reaches equilibrium at about 240 minutes. Kinetics of the sorption process on the soil is well characterized by the pseudo-second order reaction rate. Langmuir, Freundlich and D–R isotherm models are fitted for the sorption of Cu2+, Pb2, Zn2+, and Cd2+ ions onto the soil. The constants of all models were calculated for each metal ion and compared. It indicated clear differences between the sorption characteristics of Cu2+, Pb2+, Zn2+, and Cd2+ ions on the sewage irrigated soil.
