Synthesis of a Novel Water‐Soluble Graft Copolymer for Mineral Ore Beneficiation and for River Water Treatment towards Drinking Water Augmentation

Abstract

In 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).

The Synergistic Effects of Al3+ and Chitosan on the Solid–Liquid Separation of Coal Wastewater and Their Mechanism of Action

“…Mahto and Mishra [ 14 ] synthesized a new type of guar gum-based flocculant (GG-g-IA) for flocculation and sedimentation experiments with kaolin and coal slurry suspensions; the flocculation efficiencies of kaolin and coal powder with the optimized GG-g-IA reached 88.15% and 81.36%, respectively. Mehta [ 15 ] synthesized a new type of carboxymethyl cellulose flocculant using conventional and microwave assistance that could achieve a maximum flocculation efficiency of 83.6% on the flocculation and sedimentation of fine coal suspensions. Although the synthetic flocculant obtained by grafting can meet coal slurry treatment requirements, the cost of grafting synthetic agents is high.…”
