  • 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.
  • Are CPAM emulsions cationic?
  • This approach overcomes the drawbacks of traditional optimization methods. We successfully synthesized three CPAM emulsions with a wide range of cationic degrees: low (21.85%), medium (40.25%), and high (71.17%) levels of cationic degree.
  • What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
  • How does cation monomer DMC affect CPAM reactivity?
  • The content of the cation monomer DMC directly influenced the molecular weight and cationic degree of the resulting product. The molecular weight of the CPAM decreased with an increase in cationic degree, attributed to the lower reactivity of the cation monomer compared to the acrylamide monomer.
