What is linear anionic polyacrylamide (PAM)?

Linear anionic polyacrylamide (PAM) has been used in irrigation practices as a flocculating agent to minimize water losses through seepage in earthen canals. The stability of PAM is of concern because of the possibility of acrylamide (AMD) monomer release during

Is polyacrylamide an anti-erosion additive?

Kay-Shoemake, Jeanine L., et al. Soil Biology and Biochemistry 30.13 (1998): 1647-1654. High molecular weight linear polyacrylamide (PAM) with anionic charge is added to agricultural soils as an anti-erosion additive.

Why is polyacrylamide added to agricultural soils as an anti-erosion additive?

High molecular weight linear polyacrylamide (PAM) with anionic charge is added to agricultural soils as an anti-erosion additive. Studies have shown that soil microorganisms are able to utilize PAM as a nitrogen source and that inorganic nitrogen pools are altered in some soils treated with PAM.

What is anionic polyacrylamide used for?

Anionic polyacrylamide can be used as a cytoplasm additive in the paper industry with better retention and drainage effect. It has a particularly dispersing effect for long-fiber pulp when its molecular weight is greater than 3.5 million. In addition, it can also be used as a water treatment agent.

What is the pH range of polyacrylamide?

In the pH range of 3 to 9, it can maintain a good degree of stability; at high pH, the viscosity will be increased gradually. Miscibility: in generally used concentration, polyacrylamide has miscibility with most water-soluble natural or synthetic resins, latex systems, and most of the salts.

What is polyacrylamide polymer?

Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
