  • How cationic polyacrylamide (PAMC) is prepared?
  • Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
  • Which cationic polyacrylamide is used in polymerization?
  • The utilized high-pressure ultraviolet lamp is characterized by power of 500–1000 W and predominant wavelength of 365 nm. Another cationic polyacrylamide with intrinsic viscosity of 4.2 dL g −1 was synthesized in 120 min from aqueous photo-polymerization; a 200-W high-pressure mercury lamp was used in polymerization .
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
  • Does hydrophobic association improve cationic polyacrylamide flocculation performance?
  • Yang et al. successfully synthesized a cationic polyacrylamide flocculant by grafted polymerization of DMDAAC, AM, and hydrophobic monomer butylacrylate (BA); the flocculation performance of this flocculant was evidently improved because of hydrophobic association.
