  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • Are Pam flocculants toxic?
  • The potential environmental hazard does not concern the PAM itself, which is generally considered as not toxic (Andersen 2005), but the products of PAM degradation and the residual AMD contained in the flocculants due to incomplete polymerization process (Labahn et al. 2010; Young et al. 2007; Caulfield et al. 2002).
  • Can cationic Pam flocculate particles in oil sand tailings?
  • According to researchers, even with huge MWs, cationic PAM or non-ionic PAM were unable to flocculate particles in oil sand tailings. The solid in tailings, on the other hand, could only be flocculated with anionic PAM flocculants , .
  • 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.
