Abstract
AbstractIn this research paper we endeavor to publish our work on novel non acrylamide based flocculant which does not threat any acrylamide release and thus is inherently safer. A novel flocculant ‘Polydiallyldimethylammonium Chloride grafted Carboxymethyl Cellulose [CMC‐g‐P(DADMAC)]’ was synthesized by both conventional and microwave assisted method. Both the synthesis were optimized in terms of synthesis parameters. The various grades synthesized were characterized through standard characterization techniques such as Scanning electron microscope (SEM), Fourier transformation Infrared spectroscopy (FTIR), Elemental analysis, X‐ray diffraction (XRD) analysis, Thermal gravimetric analysis (TGA) Differential scanning calorimetry (DSC) analysis etc. Further, the various grades of the graft copolymers were optimized as flocculant by ‘standard Jar test’ and ‘Settling test’ protocols in river water, Kaolin, iron ore and coal fine suspension. The maximum flocculation efficacy achieved was 80.9 % (Kaolin suspension), 83.6 % (coal fine suspension), 79.5 % (Iron‐ore suspension) and 68.3 % (River water).
