The total monomer concentration (m/m%) is the percentage of all monomers in the total mass of the reaction mixture, where m AM: m CS: m DMDAAC is 6: 4: 3.The effect of total monomer concentration on positive charge density, intrinsic viscosity, GR and GE of CS-g-CPAM was investigated at initiator dosage of 0.2%, post-polymerization temperature of 55 °C, and post-polymerization time of 24 h.
Recently, more attentions have been paid to natural polymer-based flocculants in water treatment, since they are believed to be low-cost, nontoxic, and environmentally friendly materials. In this work, strong cationic chitosan-based graft copolymer flocculants (3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CTA) modified chitosan-graft-polyacrylamide, denoted as chitosan-CTA-g-PAM) have
