  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • What is the critical pH value of Apam solution?
  • In this study, the critical pH value was approximately 3.5, indicating that the pH of APAM solution should be controlled above 3.5 from the perspective of membrane pollution mitigation. In general, the lower the critical pH value, the more conducive to the membrane fouling control.
  • What is the molecular weight of template poly (allylammonium chloride)?
  • Besides, template poly (allylammonium chloride) (PAAC) was obtained from Shandong Xintai Water Treatment (Zaozhuang, China), and its molecular weight (MW) was 4200. The above reagents were of analytical grade except for AM and SAS (technical grade).
  • What happens if Apam is neutralized by H+?
  • At this time, the negative charges of APAM were neutralized by the introduction of H +, resulting in the gradual attenuation of the diffusion layer and stern layer of the micelle. At this point, the attractive force exceeded the repulsive force, the colloid structures were destroyed, agglomeration occurred, and the turbidity point appeared [ 7 ].
