  • What is cationic polyacrylamide (CPAM) emulsifier?
  • Authors to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) emulsifier is widely applied in the wastewater treatment industry, mining industry, paper industry, cosmetic chemistry, etc.
  • Is cationic polyacrylamide emulsion a flocculant for paper mill wastewater treatment?

  • 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.
  • How does temperature affect polyacrylamide cations?
  • The polymerization was slowed down, leading to excess monomer, and the molecular weight was reduced. Based on the response surface methodology in Figure 10 a,b,e,f, when the reaction temperature increased from 55 °C to 60 °C, the molecular weight of polyacrylamide cations increased rapidly, and reached its maximum at 60–62 °C.
