  • What is anionic polyacrylamide (HPAM)?
  • 1. Introduction Anionic polyacrylamide (HPAM) is a linear polymer flocculant that has been used in clarifying slime water. (1−4) The carboxyl side chain of HPAM is negatively charged in an alkaline environment, and the suspension is clarified by an adsorption bridge.
  • What are acrylamide and polyacrylamide used for?
  • Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
  • How is anionic polyacrylamide synthesized?
  • Synthesis mechanism The anionic polyacrylamide was synthesized by copolymerizing AM and SAS monomers. The essence of copolymerization is the free radical reaction. Thus, this chain reaction can be divided into three distinct processes: initiation, propagation, and termination.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
