  • Why is polyacrylamide a water soluble nonionic flocculant?
  • Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. Polyacrylamide is the most important water soluble nonionic flocculant because its mon-omer, acrylamide, is highly water soluble, cost-effective, and very reactive.
  • How is polyacrylamide (PAM) a polymer with high molecular weight?
  • Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method. Polyacrylamide was used as monomer, and a self-made initiator was used for polymerization under the condition of coexistence with sodium carbonate. The optimal polymerization parameters of PAM are determined: pH value of solution was 12. 3.
  • What is polyacrylamide?
  • Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
  • Why is anionic polyacrylamide chosen?
  • Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
