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 polyacrylamide used for?

Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

What is nonionic polyacrylamide?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.

What are the different types of polyacrylamide (PAM)?

According to its ionic properties, PAM is divided into three main types: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) and nonionic (Nonionic PAM, NPAM). These three types have significant differences in structure, function and application. 1. Cationic polyacrylamide (Cationic PAM, CPAM) Structure and properties:

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.
