  • 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 is a polymeric flocculant?
  • The addition of a polymeric flocculant allows for the destabilization of suspended colloidal particles, and thus significantly increases their sedimentation rate. Polymeric flocculants are generally divided into four categories, which include non-ionic, cationic, anionic, and amphoteric polymers.
  • 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.
  • Can anionic polyacrylamide be used in wastewater treatment?
  • Synthetic flocculants represented by anionic polyacrylamide (APAM) have attracted more and more attention in the field of wastewater treatment (Desai and Murthy 2012; Ma et al. 2013 ). The anionic chemical group in APAM can neutralize the positively charged colloidal particles in wastewater and make them destabilized (Zhao et al. 2018 ).
