  • 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.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • Is acrylamide a cationic flocculant?
  • The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
