Abstract: Heavy metals present in waste waters which are released into the environment by various industries have become a serious problem. This research focuses on the use of Activated Carbon from Chicken Feathers (ACCF) in the removal of Cd 2+ , Cr 3+ , Cu 2+ , Ni 2+ , Pb 2+ and Zn 2+ ions from aqueous solution. Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR) analysis was carried out on ACCF before and after biosorption. SEM analysis reveal the surface morphology of the biosorbents while FTIR analysis reveal the functional groups present which will aid adsorption. The optimisation of operational factors such as biosorbent concentration and initial metal ion concentration were investigated at physiological temperature. The optimum initial metal ions concentration and biosorbent concentration were therefore determined. The experimental data obtained for Cd 2+ , Cr 3+ , Cu 2+ , Ni 2+ , Pb 2+ and Zn 2+ sorption were treated using Langmuir, Freundlich and Temkin isotherms and the data fitted well into the langmuir isotherm model for Cu(II), Ni(II) and Pb(II). Also the data obtained fitted well into Freundlich and Tempkin isotherm models for Cd(II), Cu(II) and Pb(II). This study demonstrates the efficiency and effectiveness of ACCF as biosobent for the removal of Cd 2+ , Cr 3+ , Cu 2+ , Ni 2+ , Pb 2+ and Zn 2+ from aqueous solution.
