Abstract
The search for a sustainable and nontoxic polymeric product has fired an intense research in the field of graft copolymers. This study endeavor to create a polyacrylamide free novel flocculant which showed efficient behavior towards water and wastewater treatment and for mineral ore beneficiation. We synthesized the novel graft copolymer - Poly Diallyl Dimethyl Ammonium Chloride (DADMAC) grafted polyvinyl pyrrolidone (PVP-g-pDADMAC) via graft polymerization route by microwave assisted method. The synthesized novel cationic graft co-polymer has been characterized by elemental analysis, FTIR spectroscopy, intrinsic viscosity measurement, molecular weight determination, and scanning electron micrograph (SEM), taking PVP as reference. The effects of reaction parameters onto the percentage grafting have been studied. The applicability of these grafted polymers as flocculant for the treatment of municipal sewage waste water as well as for mineral ore beneficiation and for suppression of nanopollutant like multi-walled carbon Nano-tubes (MWCNTs) (as nano scavenger) from water systems were also investigated.
