  • What is cationic polyacrylamide used for?
  • used for domestic sewage and organic wastewater treatment, Cationic polyacrylamide products showed cationic in acid or alkaline medium, so it will be the good effect of flocculent and sedimentation, clarification for treating the wastewater in which the suspending articles is with a negative charge.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (cPAM), a linear water-soluble and high-molecular polymeric compound with cationic charges, can effectively enhance solid-liquid separation through charge neutralization and interparticle bridging and is widely used worldwide ( Campos et al., 2008; Dai et al., 2014).
  • How is cationic polyacrylamide obtained?
  • In the photoinitated polymerization method (Fig. 4), the cationic polyacrylamide is obtained by photoactivation of monomer solution. This synthesis technique is characterized by many advantages: operation simplicity, easy control, low cost, and obtained product has high purity [11, 12].
  • What are the different types of cationic polyacrylamide synthesis technologies?
  • There are four main kinds of cationic polyacrylamide synthesis technologies: in aqueous solution, in dispersion, by inverse emulsion, or through photoinitiated polymerization . These methods had experienced numerous developments and modifications such as free radical copolymerization or grafting processes .
