  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • What are some examples of anionic polymer flocculants?
  • Representative anionic polymer flocculants are as follows: (1) partially hydrolyzed polyacrylamides, (2) copolymers of acrylamide and acryl acid soda, (3) copolymers of acrylamide and acrylamide-2-methyl-propan sulfonic soda (AMPS), and (4) poly (sodium acrylate).
  • Do anionic polymer flocculants promote aggregation?
  • Owing to their high molecular weight of 10–20 million, anionic polymer flocculants can promote aggregation effectively at the amounts of several ppm for wastewater. The aggregation properties depend on pH, because the dissociation degree of anionic groups in the anionic polymer changes according to pH.
  • Which polymers are used in TPAs-U self-assembly of anionic flocculants?
  • In this study, the novel template polymerization and ultrasonic initiation system were applied in the self-assembly of anionic flocculants (TPAS-U) using poly (allylammonium chloride) (PAAC) as template, acrylamide and sodium p-styrene sulfonate as monomers.
