How to prepare flocculant of cationic polyacrylamide PAMC?

Raw materials Flocculant of cationic polyacrylamide PAMC was prepared in our laboratory through low-pressure ultraviolet initiation by copolymerization of acrylamide and [2- (methacryloyloxy) ethyl] trimethyl ammonium chloride.

What is cationic Pam?

Cationic PAM can rapidly adsorb negatively charged particles in water, forming large flocs and effectively improving flocculation efficiency. Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment.

How cationic polyacrylamide (PAMC) is prepared?

Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.

What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

How do cationic polyacrylamide type flocculants compare with reverse demulsifiers?

Three cationic polyacrylamide type flocculants were paired with reverse demulsifiers to assess the synergistic separation performance. Their main differences are the active component content, molecular weight, and charge density. The same OPW with the oil content of 665 mg/L was used for evaluation.

How are cationic monomers synthesized in PAMC flocculants?

In this study, the flocculants of PAMC with different cationic monomer contents were synthesized through low-pressure initiation and were characterized through FTIR, 1 H NMR, TG/DTA and ZP analysis.
