Differences Between Cationic PAM and Anionic Polyacrylamide
At present, the PAM water treatment is generally anionic type. That is, adding an appropriate amount of sodium hydroxide to hydrolyze, so that part of the amide group becomes carboxyl, and the degree of hydrolysis is proportional to the amount of sodium hydroxide added.

Get PriceWhat 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 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:
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.
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).
Why is anionic polyacrylamide important in water treatment?
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. Anionic polyacrylamide plays a significant role in water treatment in the following aspects:
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.
