High performance flocculating agents based on cationic polysaccharides in relation to coal fine suspension

Five polysaccharides namely amylopectin, amylose, glycogen, guar gum and starch have been cationized by grafting with N-(3-chloro-2-hydroxypropyl) trimethyl ammonium chloride and studied for their flocculation behaviors. Of them, cationic glycogen (Cat Gly) is found to be the best for flocculation o...

Description
Summary:Five polysaccharides namely amylopectin, amylose, glycogen, guar gum and starch have been cationized by grafting with N-(3-chloro-2-hydroxypropyl) trimethyl ammonium chloride and studied for their flocculation behaviors. Of them, cationic glycogen (Cat Gly) is found to be the best for flocculation of coal suspended sample amongst cationic polysaccharides. Cat Gly was compared with some of the commercial flocculants.
