cationic kraft lignin-acrylamide copolymer as a flocculant,in this paper, acrylamide (am), (2-methacryloyloxyethyl) trimethyl ammonium chloride (dmc) and kraft lignin (kl) were polymerized in an aqueous solution to produce a water-soluble lignin-based copolymer. two cationic kad polymers, with the same molecular weight, but different charge densities, were used as flocculants for simulated clay

What are cationic polyacrylamide copolymers?
Cationic polyacrylamide copolymers (PAM) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
What are cationic polyelectrolytes?
Cationic polyelectrolytes are water-soluble polymers bearing positive ionic groups along the backbone or in side chains. These cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques.
Are cationic polyacrylamide copolymers harmful to the environment?
Cationic polyacrylamide copolymers (PAM) are used for sludge dewatering in municipal wastewater treatment and may enter the environment through the spread of sludge on agricultural fields. There is concern about the degradation of PAM in soils because little is known.
What is polyacrylamide?
Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
