Synthesis and Characterization of Poly (Acrylamide- - SciELO

The goal of the paper was to prepare a class of flocculants by free-radical copolymerization of acrylamide with acrylic acid in aqueous solutions in the presence/absence of potassium persulphate as initiator. Reaction medium was submitted to electron beam treatment of 0.6 to 1.5 kGy in atmospheric conditions and at room temperature.

What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.

Does polyacrylamide structure affect flocculation of bentonite clay?

Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.

What is the flocculation ability of Pam-hade compared with poly acrylamide-N-acryloyl-?

The flocculation ability of the novel PAM-HADE was compared with that of poly (acrylamide- N -acryloyl-1,2-diaminoethane hydrochloride) (PAM-LADE) as its linear alternative in 1 wt% kaolinite suspension.

Is acrylamide a cationic flocculant?

The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .

How effective is PAMC flocculation in turbid water clarification?

Chemical and morphology structures of PAMC were characterized and analyzed. Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content.

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.
