What are anionic polyacrylamides?

Anionic polyacrylamides (PAMs) are a class of synthetic water-soluble polymers (composed of long chains of acrylamide monomer) used as flocculants. They are available in dry powder form, liquid emulsion, and gelatinous blocks.

Is anionic polyacrylamide toxic?

Anionic polyacrylamide has no systemic toxicity to aquatic organisms or micro-organisms. The polymer is much too large to be absorbed into tissues and cells. The functional anionic groups do not interfere with the functioning of fish gills or daphnia respirators.

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 is anionic polyacrylamide used for?

Anionic Polyacrylamide is widely used in Oil & Gas, water treatment, textile, printing and dyeing, papermaking, mineral processing, coal washing, medicine, sugar, breeding, building materials, agriculture and other industries. It is known as the most widely used additive.

Can anionic polyacrylamide be used as a mediator in environmental remediation?

Uncovering an accessible and cheap material as mediator becomes a top priority, which can potentially improve the activity of heterojunction in environmental remediation. Anionic polyacrylamide (APAM) is a hydrophilic polymer which is easy to be carbonized (Choi et al., 2004).

What are the different types of anionic polyacrylamide synthesis technologies?

The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
