Effect of impregnation of activated carbon with chelating polymer on adsorption kinetics of Pb2+

The effects of polyethyleneimine (PEI) impregnation on the Pb2+ adsorption kinetics of palm shell-activated carbon and pH profile of bulk solution were investigated. Adsorption data were fitted to four established adsorption kinetics models, namely, pseudo-first-order, pseudo-second-order, Elovich e...
