  • Can cationic polyacrylamides be used in water treatment?
  • This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of <5 μg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water.
  • What is nonionic polyacrylamide?
  • Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
  • Which polymer is used in water treatment?
  • Polymers used in water treatment are characterized by their molecular weight, the predominant sign of their charged sites (anionic, cationic, or nonionic), and their charge density. A simple polymer is nonionic polyacrylamide, the homopolymer formed from acrylamide monomer.
  • Is acrylamide a cationic polymer?
  • Acrylamide monomer is used to make anionic and cationic copolymers, as well as nonionic polyacrylamide. Nonionic polyacrylamide may also be hydrolyzed to form an anionic polymer. Epichlorohydrin is used to make various cationic copolymers, notably epichlorohydrin-dimethylamine copolymer (epi-DMA).
