  • What is organic polymer flocculant cationic polyacrylamide (CPAM)?
  • The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
  • 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.
  • Why are cationic surfactants used in polyacrylamide adsorption?
  • This is due to the addition of cationic surfactants in the suspension, as cationic surfactants can assist the polyacrylamide adsorption of suspended particles in wastewater through electrostatic action, whereby the more negatively charged suspended particles are in wastewater, the more pronounced is this auxiliary flocculation effect [ 36 ].
  • Is CPAM a cationic microblock?
  • It has been shown that the flocculation performance of CPAM is related to the distribution and sequencing of cationic units in the molecular chain (Feng et al. 2018b). The continuous arrangement of cationic units in CPAM can form cationic microblock structure.
