  • What is amphoteric polyacrylamide (ampam)?
  • agents for enhanced oil recovery, drainage, and retention aids in the paper manufacturer, etc.[1–5] Amphoteric polyacrylamide (AmPAM) [6,7] carries anionic and cationic charge group on the polymer back-bone, which can adsorb both organic and inorganic sus-pension substances.
  • 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 type of polymer is a flocculant?
  • Most flocculants are acrylamide-based polymers and may be available in anionic, cationic, nonionic, or amphoteric forms 18. The copolymer adsorption on the surface of montmorillonite particles generally depends on the functional group of monomers and charge distribution 19, 20, 21.
  • 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 .
