What are the main differences between anionic and cationic ...
Anionic polyacrylamide has a negative charge due to the presence of anionic groups (such as carboxylate or sulfate groups), while cationic polyacrylamide has a positive charge resulting from cationic groups (such as amino or quaternary ammonium groups).

Polyacrylamide - Wikipedia
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Polyacrylamide is a polyolefin.

Get PriceWhat is cationic polyacrylamide?
Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
What is cationic polyacrylamide (CPAM)?
Cationic polyacrylamide (CPAM) is a type of polyacrylamide that has positively charged functional groups on its molecular chains. It is widely used in various industries for its unique properties. Some of the common usages of cationic polyacrylamide are:
Is cationic polyacrylamide soluble in water?
Cationic polyacrylamide (CPAM) is highly soluble in water and can form clear solutions at low concentrations.Due to the positively charged functional groups, Cationic polyacrylamide (CPAM) can attract and bond with negatively charged particles and suspended solids in water, leading to flocculation and sedimentation.
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.
Why is cationic polyacrylamide used in oil & gas industry?
Oil and gas industry: Cationic polyacrylamide (CPAM) is used in the enhanced oil recovery process to increase the viscosity of injected water and improve the displacement efficiency of oil. CPAM can reduce the mobility of water and improve the sweep efficiency of oil, leading to increased recovery rates and reduced production costs.
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.
