Preparation and flocculation properties of biodegradable konjac glucomannan-grafted poly(trimethyl allyl ammonium chloride)

Preparation of konjac glucomannan-grafted poly(trimethyl allyl ammonium chloride) (KGM-g-PTMAAC) was carried out using KGM as polysaccharide matrix and TMAAC as cationic comonomer to develop biodegradable flocculants. The structure of KGM-g-PTMAAC was characterized by FTIR, 13C solid-state NMR, elemental analysis (EA) and SEM. Thermal properties of KGM-g-PTMAAC were studied by thermal gravimetric (TG) analysis. In addition, flocculation...
