Anionic and cationic polyacrylamide are two types of polyacrylamide polymers with different charge properties. Here are the main differences between them: 1. Charge properties: The key distinction lies in their charge characteristics. Anionic polyacrylamide has a negative charge due to the presence of anionic groups (such as carboxylate or sulfate groups), while cationic polyacrylamide has a ...

In addition to removing contaminants in water and sewage with this method, the use of polyacrylamide is very effective in improving the color and clarification of water. In fact, PAM, as a cationic polymer, is able to increase the rate of bacterial deposition and help improve the uptake of bacterial cells, suspended solids, and cell components.

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 .

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 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.

Can UV-initiated template polymerization prepare a novel anionic polyacrylamide with a microblock structure?

E-mail: zhl6512@126.com; Fax: +86 23 65120827; Tel: +86 23 65120827 Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure.

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.
