  • Can cationic polyacrylamide be used in oilfield wastewater treatment?
  • Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
  • What is cationic polyacrylamide (C-PAM)?
  • Cationic polyacrylamide (C-PAM), copolymerized from acrylamide and substituted acrylate or acrylamide segments, offers an alternative to PHPA and exhibits high stability under high TDS conditions 28.
  • Which cationic polyacrylamide is synthesized through UV initiation?
  • Recently, Ma et al. used acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride (DMC) to synthesize a novel cationic polyacrylamide (CPAM) through low-pressure ultraviolet (UV) initiation.
  • 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 ].
