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...

Polyacrylamide

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. [1] Physicochemical properties [ edit]

Biodegradation of Polyacrylamide and Its Derivatives

The monomer acrylamide is toxic to most microorganisms, however, some bacteria and fungi could degrade it using amidases that deaminate acrylamide to acrylic acid and ammonium, and further utilize acrylic acid to produce CO 2 and water. Some fungi and yeasts could degrade 60¨C80% of acrylamide.

Polyacrylamide. Residual Acrylamide In studies on Polyacrylamide (Dow 1954), the average con-centrations of acrylamide were found to be less than 0.01%. In data provided to the Cosmetic, Toiletry, and Fragrance As-sociation (CTFA) in 1990, then current manufacturers of Poly-acrylamide listed a maximum of 0.1% for residual acrylamide

Acrylamide in food: Progress in and prospects for genetic and agronomic

Although polyacrylamide is considered safe, it may contain a small concentration of monomeric acrylamide as an impurity, and monomeric acrylamide is, therefore, a potential water pollutant, with a guideline value for its presence in drinking water set by the World Health Organisation at 0.5 ¦Ìg per litre, or parts per billion.
