polyacrylamide degradation and its implications in environmental

Polyacrylamide degradation and its implications in environmental

The term ¡°polyacrylamide¡± is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which defines...

Biodegradation of Polyacrylamide and Its Derivatives

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed.

Degradation of Polyacrylamide (PAM) and methane production by

Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The impact or fate of PAM in AD under thermophilic conditions is still unclear. This study mainly focuses on PAM degradation and enhanced methane production

Partially hydrolyzed polyacrylamide: enhanced oil recovery applications

Polyacrylamide and partially hydrolyzed polyacrylamide Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 ¡Á 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012 ; Joshi & Abed, 2017 ).

isolation and characterization of polyacrylamide-degrading bacteria

Isolation and Characterization of Polyacrylamide-Degrading Bacteria

Polyacrylamide (PAM) is a water-soluble polymer that is usually produced through the polymerization of acrylamide with one or more copolymers. The amide groups of PAM form hydrogen bonds in aqueous solutions, and high-molecular-weight PAM is an effective flocculant of suspended solids in water via charge neutralization and interparticle bridging [ 1 ].

Acrylamide in Environmental Water: A Review on Sources

Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 ¡ãC for elongated time. Researches in rats have demonstrated that acrylamide

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) 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.

Polyacrylamide - an overview | ScienceDirect Topics

Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Polyacrylamide undergoes thermal degradation at 175 to 300¡ãC (Smith
