  • What is anionic polyacrylamide (Apam)?
  • Anionic Polyacrylamide (APAM): APAM is a water-soluble high-molecular-weight polymer used extensively for coagulation and sedimentation in various industrial wastewater treatments, such as steel plant effluents, electroplating wastewater, metallurgical wastewater, and coal washing wastewater.
  • What is the ionicity of Apam and CPAM?
  • When two or three of the eight amido functional groups are replaced, the ionicity of the APAM or CPAM obtained is 25.0% or 37.5%, Na ions were added to APAM and Cl ions to CPAM to compensate for the charge of the ionized PMA molecules. The montmorillonite model is consistent with the Na-rich montmorillonite sample used in the QCM-D experiments.
  • What is the difference between Apam and CPAM CWS?
  • When the slurry was exerted with a shear force, the viscosity of CWS was decreased due to the release of a big volume of trapped free water. Thus, the rheological behavior of APAM-cws was the same as Blank-cws. For CPAM-cws, the slurry was still characterized as the pseudoplastic fluid, but this feature was weakened a lot.
  • Is CPAM better than Apam?
  • Contrary to APAM, CPAM shows a good adsorption performance on the montmorillonite surface. However, the configuration of the adsorption layer changes with the variation of the polymer ionicity. Moreover, CPAM is concentrated at 3 Å from the surface of the montmorillonite. Regarding the 12.5% ionicity, a tight adsorption layer of the CPAM is formed.
