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]

Acrylamide in Environmental Water: A Review on Sources, Exposure, and Public Health Risks | Exposure and Health

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.

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes

Microorganisms have been shown to utilize, not only acrylamide, but also PAM and its derivatives as the sole source of nitrogen and/or carbon under aerobic as well as anaerobic conditions. Microbial degradation lowered the molecular weight of the polymer, the viscosity, and the amide nitrogen was degraded to ammonia.

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.
