Impact of anionic polyacrylamide on stability and surface

The stability mechanism and thermal properties of the system alumina–anionic polyacrylamide (PAM) was studied. The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined.

Anionic polyacrylamide - wastewater treatment chemicals

Anionic polyacrylamide is the kind of wastewater treatment chemicals which is water-soluble linear polymer synthesized with high degree of polymerization. Anionic polyacrylamide powder is easily soluble in water and almost insoluble in common organic solvents such as benzene, ether, lipids and acetone. Anionic polyacrylamide molecular chain contains a certain amount of polar groups capable of adsorbing suspended solid particles in water, so it is especially suitable for water treatment with

Polyacrylamide

The anionic form of linear, water-soluble polyacrylamide is frequently used as a soil conditioner on farm land and construction sites for erosion control, in order to protect the water quality of nearby rivers and streams. The polymer is also used to make Gro-Beast toys, which expand when placed in water, such as the Test Tube Aliens. Similarly, the absorbent properties of one of its copolymers can be utilized as an additive in body-powder.
