  • 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.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is one of the most widely applied polymers due to its high performance in flocculation, sludge dewatering, and harvesting microalgae [ 6, 7, 8, 9, 10, 11, 12, 13 ].
  • What is the particle size distribution of cationic polyacrylamide nanoparticles?
  • The results of the particle size distribution of the cationic polyacrylamide nanoparticles showed that the average diameter of the polymer particles was 32.2 nm, while the particle size distribution was from 25 to 200 nm ( Figure 7 ).
  • What is the molecular mass distribution of CPAM?
  • The results showed that the number–average molecular weight (M n) and the weight–average molecular weight (M w) of CPAM were about 8,518,300 g/mol and 19,035,000 g/mol, respectively. The molecular mass distribution was expressed as a polydispersity index (PDI). (M w /M n) = 2.23.
