Cationic polyacrylamide copolymers (PAMs): environmental half life

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting

Polyacrylamide, or PAM, is made from the acrylamide monomer. Although PAMs are not toxic, the starting building block, acrylamide, is one of the substances of very high concern (SVHC) and is included in the candidate list for authorization [ 6, 7, 8 ].

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. [1] Physicochemical properties [ edit]

thermal decomposition of acrylamide from polyacrylamide

Thermal decomposition of acrylamide from polyacrylamide

The thermal decomposition of polyacrylamide (PAA) has received continued attention in the literature [1¨C5] for the following reasons: (i) PAA is used as an important thermoplastic material in many industries; (ii) the acrylamide monomer, which is a neurotoxin and carcinogen, can be present in small amounts in polymerized acrylamide; and (iii) PAA used in the food industry may contaminate

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.

Sun et al. grafted acrylamide and [2-(acryloyloxy)ethyl] trimethylammonium chloride onto chitosan by UV initiation to control polymer microstructure and charge density of the flocculant, since acrylamide can form high molecular weight polymers and the quaternary ammonium monomer imparts cationicity to the flocculant. 73 They used the flocculant with CaCl 2 to treat zinc phosphate

As a temperature-resistant and salt-resistant polymer, acrylamide and 2-acrylamide-2-methylpropane sulfonic acid (abbreviated as AM-AMPS) copolymer is currently widely used in drilling, water control and oil production stabilization, enhanced oil recovery and other fields, but its stability under high temperature has been less studied. The degradation process of the AM-AMPS copolymer solution
