  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
  • Can cationic Pam flocculate particles in oil sand tailings?
  • According to researchers, even with huge MWs, cationic PAM or non-ionic PAM were unable to flocculate particles in oil sand tailings. The solid in tailings, on the other hand, could only be flocculated with anionic PAM flocculants , .
  • What are cationic polymer flocculants?
  • Representative cationic polymer flocculants include (1) copolymers of acrylamide and acryloyloxyethyl trimethylammonium chloride, (2) poly (methacryloxyethyl trimethylammonium chloride), and (3) polyamidine. Their molecular weight ranges from several million to less than 20 million.
  • 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).
