What is cationic polyacrylamide?

Generally, cationic polyacrylamide is copolymerized by acrylamide (AM) and cationic monomers in an aqueous solution. Among various cationic monomers, (3-acrylamidopropyl) trimethyl ammonium chloride (ATMAC) is the first used cationic monomer because of the rich amine groups.

Can a polyacrylamide flocculant be synthesized by low-pressure initiation?

A novel flocculants of PADC was synthesized through low-pressure initiation. Hydrophobic monomer of CDEA was introduced to synthesis of polyacrylamide. Intrinsic viscosity and positive charge density of PADC was investigated. Chemical structures of PADC were characterized and analyzed.

Which monomer is used in synthesis of polyacrylamide?

Hydrophobic monomer of CDEA was introduced to synthesis of polyacrylamide. Intrinsic viscosity and positive charge density of PADC was investigated. Chemical structures of PADC were characterized and analyzed. Flocculation performance and mechanism were evaluated and summarized.

Does hydrophobic association improve cationic polyacrylamide flocculation performance?

Yang et al. successfully synthesized a cationic polyacrylamide flocculant by grafted polymerization of DMDAAC, AM, and hydrophobic monomer butylacrylate (BA); the flocculation performance of this flocculant was evidently improved because of hydrophobic association.

Can cationic polyacrylamide be used for oily wastewater treatment?

Zhao C, Zheng H, Gao B, Liu Y, Zhai J, Zhang S, Xu B (2018) Ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: Enhanced interaction between the flocculant and contaminants.

Why is cationic polyacrylamide used for turbidity separation?

Meanwhile, effective organic polymer flocculant, especially cationic polyacrylamide (CPAM), was developed and extensively used for turbidity separation because of their satisfactory solid-water separation performance . Generally, cationic polyacrylamide is copolymerized by acrylamide (AM) and cationic monomers in an aqueous solution.
