  • How to synthesize amphoteric polyacrylamide flocculants?
  • Copolymerization of AM with various functional monomers or betaine-based monomers is also a general way to synthesize amphoteric polyacrylamide flocculants. Zhu et al. used amphoteric polyacrylamide (AmPAM) obtained by the copolymerization of AM, AA and methyl acrylic acid ethyl trimethyl chloride ammonium for treating tannery wastewater [ 77 ].
  • What is amphoteric polyacrylamide (ampam) citation?
  • Amphoteric polyacrylamide (AmPAM) Citation [6,7] carries anionic and cationic charge group on the polymer backbone, which can adsorb both organic and inorganic suspension substances. So it is more suitable to deal with occasions that other flocculants cannot treat.
  • What is the retention mechanism of amphoteric polyacrylamide?
  • The retention mechanism of the novel amphoteric polyacrylamide is that the anionic group first neutralizes the cationic waste in the paper material to reduce the electrostatic attraction resistance between the cationic group and the pulp fibers.
  • Is acrylamide a cationic flocculant?
  • The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
