- 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 [ , , ].
- Is Apam a uniform polymer?
- The polyacrylamide is a uniform and unitary polymer. PAM has a neat smooth surface as its SEM images unfold at 2500x and 4000x. However, the surface of APAM was much rougher. Hills and valleys could be observed in its SEM images due to the interaction of chemical groups between AM and SAS.
- How is anionic polyacrylamide synthesized?
- Synthesis mechanism The anionic polyacrylamide was synthesized by copolymerizing AM and SAS monomers. The essence of copolymerization is the free radical reaction. Thus, this chain reaction can be divided into three distinct processes: initiation, propagation, and termination.
- Does microblock structure enhance reactivity and copolymerization of Apam-T?
- Anionic polyacrylamide with regular microblock structure was synthesized. The reactivity and copolymerization degree were enhanced by microblock structure. The turbidity removal of APAM-T for hematite wastewater could reach 98.22 %. The charge neutralization and bridging adsorption capacity of APAM-T were enhanced.
