ABSTRACT
Various grades of poly-(acryl amide) grafted casein (CAS-g-PAM) were synthesized by microwave-assisted method using chemical free radical initiator (e.g., ceric ammonium nitrate). The grafting of the poly (acryl amide) chains on the casein backbone was confirmed through intrinsic viscosity study and other physicochemical characterization techniques like FTIR spectroscopy, elemental analysis (C, H, N, O and S), scanning electron microscopy (SEM) and number average molecular weight determination through osmometry. The intrinsic viscosity and number average molecular weight of casein appreciably improved on grafting of poly (acryl amide) chains. Further, flocculation efficacy of the tailor-made graft copolymer was studied in kaolin suspension and through jar test procedures, towards possible application as flocculent. Further, flocculation efficacy of the ‘best grade’ (as determined by ‘jar test’ in kaolin suspension) in wastewater was studied for possible application in reduction of pollutant load of wastewater.
