  • What is the rate of degradation of polyacrylamide (PAM) by oxidation?
  • Previous studies have shown high rates of PAM degradation by oxidation. concentrations by more than 95%. coagulation. Membrane processes such as RO can provide treated be high. Detailed cost analyses will need to be performed to polyacrylamide.
  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • Why is polyacrylamide a high molecular weight polymer?
  • As the representative material, high molecular weight partially hydrolyzed polyacrylamide, because of its extremely high molecular weight and the electrostatic repulsion between the negative carboxylate charges along the polymer chain [ 1, 2 ], it can directly increase the viscosity of the oil recovery water and pump out feasibly.
  • What is high molecular weight partial hydrolysis polyacrylamide (HPAM)?
  • High molecular weight partial hydrolysis polyacrylamide (HPAM) is widely used in the oil recovery, and however, these high molecular weight HPAM will experience a rapid degradation when Fe 2+ was existed in the system. Some studies have implied it was a radical assisted decomposition process.
