A novel amphoteric copolymer flocculant was synthesized by incorporating a cationic moiety 2,3-epoxypropyl trimethyl ammonium chloride (GTA) and an anion moiety phosphate onto the backbone of starch with microwave radiation. The synthesized starch copolymer was characterized and examined by FTIR, (1)H NMR spectroscopy, scanning electron microscopy (SEM), molecular mass and polydispersity, swelling power and solubility index. Flocculation performance was evaluated in 50mg/L methyl violet… CONTINUE READING
