  • 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)?
  • J. Pharm. Biopharm.54 (2002) 41–50. 10.1016/S0939-6411 (02)00036-X Search in Google Scholar Cationic polyacrylamide (CPAM) was prepared in aqueous solution by free radical polymerization of methacryloyloxy ethyl trimethylammonium chloride (DMC) and acrylamide (AM). A redox initiator system was used.
  • Can cationic flocculants be synthesised by UV-induced polymerization?
  • 4. Conclusions This study demonstrated facile synthesis of two cationic flocculants via UV-induced polymerization of monomers [2- (acryloyloxy)ethyl]trimethylammonium chloride and (3-acrylamidopropyl)trimethylammonium chloride for harvesting freshwater green microalgae ( C. vulgaris) and marine red microalgae ( P. purpureum ).
  • 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.
