  • What is polyamine used for?
  • Polyamine is a low molecular weight cationic water-soluble liquid polymer, which can be used as coagulant in solid-liquid separation process in water treatment industry, charge neutralizer and adhesive control agent in paper industry.
  • Can cationic polymers reduce nitrosodimethylamine formation?
  • Drinking water treatment relies upon chemical addition, including cationic polymers (e.g., polyDADMAC), to achieve turbidity and pathogen removal. The present study shows the contributions of cationic polymer to nitrosodimethylamine (NDMA) formation, and how polyDADMAC purification can dramatically reduce NDMA formation.
  • Can polymeric polyamine coagulant based on epichlorohydrin and dimethylamine be used in Remazol?
  • In the present study, polymeric polyamine coagulant based on epichlorohydrin and dimethylamine was synthesized after optimization of the process parameters using response surface methodology by Box-Behnken design matrix, characterized, and used for treatment of simulated reactive dye (Remazol Red) solution.
  • What is the removal efficiency of polyamine coagulants?
  • The removal efficiency of polyamine at the dosage of 180 mg L −1 was 89%. While at the same dosage, the color removal efficiencies of PAC approached 25%. Generally, coagulants remove contamination from water and wastewater by charge neutralization and bridging action.
