Beneficial effect of chitosan-g-polyacrylamide copolymer in removal of heavy metals from industrial dye effluents

Water is an essential matter to human and other living organisms. Chitin, chitosan, poly acrylamide polymers are individually used for waste water treatment due to biocompatibility and inexpensive. In the present study graft copolymer of chitosan with acrylamide has been synthesized in the presence of nitrogen using ceric ammonium nitrate, nitric acid redox system with UV irradiation. The synthesis copolymer subjected to various analytical techniques such as fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) to confirm the formation of copolymer. The cross linkage between chitosan and polyacrylamide was analysed and proven with FTIR and DSC. The SEM results shown the formation and strong chemical interaction between chitosan and polyacrylamide. The prepared graft copolymer was subjected to industrial dye effluent and result revealed that the copolymer prepared is excellent in removing all the polluted ions including heavy metals. Hence, chitosan-g-polyacrylamide copolymer could open way for waste water treatment in industrial level.
