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.

What is anionic polyacrylamide polymer (PAAM)?

Anionic polyacrylamide polymer (PAAM) is a commonly used synthetic polymer in the coagulation-flocculation treatment process for industrial wastewater .

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.

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.

What are acrylamide and polyacrylamide used for?

Both acrylamide and polyacrylamide are used mainly in the production of flocculants for the clarification of potable water and in the treatment of municipal and industrial effluents. They are also used as grouting agents in the construction of drinking-water reservoirs and wells (IPCS, 1985).
