| Abstract | ||
| The removal of Cd(II) onto granular activated carbon (GAC) and kaolinite in single component systems has been studied using batch adsorption. Batch adsorption studied were carried out under various amount of GAC and Kaolinite, Cd(II) ion concentration, pH and contact time. The experimental data was analyzed by Langmuir, Freundlich and Redlich- Peterson isotherms. The equilibrium adsorption capacity of Cd(II) was determined from Langmuir isotherm equation and found to be 3.002 mg/g for GAC and 1.837 mg/g for kaolinite. Pore diffusion model for batch adsorption is used to predict the concentrationdecay curve for adsorption of Cd(II) onto GAC and kaolinite. | ||
