Polyacrylamide degradation and its implications in environmental

The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21 ...

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

ANIONIC POLYACRYLAMIDE

It is known as the most widely used additive. Anionic polyacrylamide is the generic name for a group of very high molecular weight macromolecules produced by the free-radical polymerization of acrylamide and an anionically charged comonomer, mainly the sodium salt of acrylic acid, sodium acrylate.

most general shade is off-white, some are creamy yellowish, some greenish and dewatered emulsions (DW) are milky white. As emulsions are multi-phase systems and are composed of sometimes more than 10 components, slight color changes which are impossible to control may occur. Variations can come from stabilizers, residues of the

Best Practices Guidance for the Use of Anionic Polyacrylamide on

PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. The process is known as polymer bridging. One of the most common polymer flocculants on the market. Common uses of PAM as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds.

Fabricating an anionic polyacrylamide (APAM) with an anionic block

On one hand, the particles with opposite charge can be thoroughly neutralized and destablized by the anionic chemical group. 11,12 On the other hand, these destabilized particles will be captured by the molecule chain of APAM to agglomerate and form large and compact flocs, and thus flocculation occurs. 13 During the solid-water separation process, the main mechanisms involved are charge ...

Manganese peroxidase (Mn P) is capable of effectively degrading anionic polyacrylamide (HPAM). However, the interaction of Mn P with HPAM at molecular level is lacking until now. Here, the HPAM model compounds, HPAM-2, HPAM-3, HPAM-4, and HPAM-5, were selected to reveal their binding mechanisms with Mn P. The results showed that the most suitable substrate for Mn P was HPAM-5, and the main ...
