The chemical principle of anionic polyacrylamide (APAM) in paper mill wastewater treatment is mainly based on the functions of electrical neutralization and adsorption bridging. Specifically, the polar groups on the APAM molecular chain can adsorb negatively charged suspended particles in water, and through electrical neutralization, bridge the particles to form larger flocs.

Can anionic polyacrylamide be used in water treatment?

What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.

Can anionic polyacrylamide be used as a coagulant in water treatment sludge?

Also, using anionic polyacrylamide (APAM) as a coagulant in the dewatering process of water treatment sludge has been a regular practice to accelerate the dewatering process and decrease the size of dewatering tanks or ponds in large-scale drinking water treatment plants.

What are the different types of anionic polyacrylamide synthesis technologies?

The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.

Can polyaluminium chloride and anionic polyacrylamide remove CD 2+ and Zn 2+?

Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd 2+ and Zn 2+ from aqueous solutions by batch adsorption studies.

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.

Is Apam-t a novel anionic polyacrylamide?

Conclusion APAM-T is a novel anionic polyacrylamide which has been successfully synthesized by ultrasonic initiated template copolymerization. Characterization results showed the evidence of the microblock structure’s existence and the enhancement of copolymerization degree by adding the template.
