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.

How does anionic polyacrylamide (Apam) work?

Anionic polyacrylamide (APAM) carries a negative charge, and its molecular chain contains polar groups such as carboxyl groups. These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension.

Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

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.

What is anionic polyacrylamide used for?

Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater. Compared to cationic PAM, anionic polyacrylamide is usually less expensive and is suitable for large-scale use.

What is polyacrylamide (PAM) used for?

In water treatment and industrial production, polyacrylamide (PAM) is widely used as an important flocculant in wastewater treatment, pulp production, ore processing, and other fields. Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM).
