Abstract

The adsorption property of Cu2+ in aqueous solution by carbonaceous adsorbent made by sludge was studied. Under static conditions, the influences to the adsorption properties by the dosage of adsorbent, adsorption time, concentration of Cu2+, adsorption temperature, pH value, and other factors were systematically studied. The adsorption kinetics of the carbonaceous adsorbent was analyzed, and its adsorption properties were primarily discussed. The research results show that the carbonaceous adsorbent made by sludge has strong removal efficiency of Cu2+; the adsorption process complies with the Fruendlich adsorption isotherm; and the adsorption process can be represented by first-order kinetic model.
