Description
In an attempt to develop an environmentally friendly bifunctional graft copolymer for wastewater treatment, a grafted starch with amphoteric character was prepared by grafting the mixed monomer system of acrylic acid (AAc) and N-vinylpyrrolidone (NVP) onto naturally occurring maize starch using g-irradiation, followed by amination of the produced graft copolymer with diethylene triamine (DETA) and characterized by FTIR and SEM. The prepared bifunctional graft copolymer was applied for removal of cadmium and dichromate from aqueous solution, adsorption results showed that the adsorption tendency of bifunctional copolymer towards C d is higher at ph 6 than at ph 3 and obeys freundlich isotherm, whereas the adsorption behaviour towards dichromate is higher at ph 3 compared with ph 7 and 9 and obey both Freundlich and Langmuir isotherm
