  • Which reagent is used to degrade polyacrylamide in aqueous solution?
  • Ramsden, D. K. & McKay, K. Degradation of polyacrylamide in aqueous solution induced by chemically generated hydroxyl radicals: Part I-Fenton’s reagent. Polym. Degrad. Stab. 14, 217–229 (1986). Ramsden, D. K., & McKay, K.
  • What is copper-catalyzed controlled polymerization of acrylamide?
  • Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 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.
  • Can acrylamide monomer be determined by liquid chromatography?
  • Ver Vers, L. M. Determination of acrylamide monomer in polyacrylamide degradation studies by high-performance liquid chromatography. J. Chromatogr. Sci. 37, 486–494 (1999).
