What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is a hydrophilic polymer which is easy to be carbonized (Choi et al., 2004). The amide group (−CONH 3) on APAM can form hydrogen bond with the uncondensed amine groups on surface of g-C 3 N 4 (Schwinghammer et al., 2014).

What are polyacrylamides (Pam)?

Polyacrylamides (PAM) are synthetic polymers available in both powder and liquid (emulsion) form (Needham & Doe, 1987; Chang, 1978; Donaldson et al., 1989). These polymers are manufactured in a variety of ways to yield a wide range of physical and chemical properties that make them candidates for many different oilfield applications.

What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

What is polyacrylamide used for?

Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment.

Can nonionic polyacrylamide be used as a sewage treatment agent?

Nonionic polyacrylamide can be used as a sewage treatment agent for acidic slurry, making the suspended particles flocculate and precipitate. * You have to Login or Register to download this file.
