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 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.

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 determines the molecular weight of anionic polyacrylamide?

The molecular weight is determined by the type and concentration of the reaction initiator and the reaction parameters. 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.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (APAM) is a kind of polyacrylamide (PAM) and shows electronegative which contains functional groups of sulfonic acid, phosphoric acid or carboxylic acid .

Is cationic polyacrylamide suitable for suspending materials with negative charge?

Cationic polyacrylamide is suitable for suspending materials with negative charge and organic matter.
