  • What is a polyacrylamide (PAM)?
  • 1. Introduction Polyacrylamides (PAM) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. Their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety ( Abidin et al., 2012; Acharya et al., 2010 ).
  • 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 is the molecular weight of Pam?
  • The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
  • 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.
