ANIONIC POLYACRYLAMIDE - Santos

No studies on the environmental fate of anionic polyacrylamide are available. As a high-molecular-weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate (Lyons and Vasconcellos, 1997). The environmental fate of anionic polyacrylamide will be determined primarily by adsorption (Lyons and Vasconcellos, 1997).

Polyacrylamide degradation and its implications in - Nature

Polyacrylamide (PAM) Chitosan What is Anionic Polyacrylamide? ? High molecular weight, water soluble molecule formed by polymerization of negatively charged acrylamide co-monomer. ? PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. ? The process is known as polymer bridging.

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties

Polyacrylamide (PAM) is a linear high-molecular-weight polymer that is easily soluble in water. Its aqueous solution is a nearly transparent viscous liquid. PAM is non-hazardous, non-toxic, and non-corrosive. Solid PAM exhibits moisture absorption, flocculation, adhesion, drag reduction, and thickening properties, while also having good stability.
