Removal of Cd 2+ , Pb 2+ , and Ni 2+ from aqueous solutions using cellulosegraft-acrylic acid (C-g-AA) hydrogels was investigated. Various factors affecting the adsorption capacity, such as pH, time, initial ions concentration, and competitive ions, were tested. The results showed that the adsorption of hydrogels was very pH dependent, and maximum adsorption was obtained at a pH of 5.0. The adsorption capacities of hydrogels for the heavy metal ions were 562.7 mg/g (Cd 2+ ), 825.7 mg/g (Pb 2… CONTINUE READING
