  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
  • How to improve flocculation efficiency of cationic polyacrylamide (CPAM)?
  • Among them, flocculation is an efficient and simple physicochemical method, and to be choose proper flocculant is the key factor to enhance flocculation efficiency (Li et al. 2017; Luo et al. 2013 ). Cationic polyacrylamide (CPAM) is a water-soluble linear polyelectrolyte with high molecular weight and positive charge density.
  • Is CPAM a cationic microblock?
  • It has been shown that the flocculation performance of CPAM is related to the distribution and sequencing of cationic units in the molecular chain (Feng et al. 2018b). The continuous arrangement of cationic units in CPAM can form cationic microblock structure.
  • 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.
