Polyacrylamide degradation and its implications in environmental systems | npj Clean Water - Nature

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...

The polymers tested were modified HPAM-based co-polymers functionalized with 2-acrylamido-2-methylpropane sulfonate (AMPS) monomers. The sulfonated polyacrylamide co-polymers FLOCOMB C7035, AN132 VHM, SUPERPUSHER SAV55, and THERMOASSOCIATIF were aged at 80?C for 90 days with and without an antioxidant. The evaluations were conducted in

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes

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. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown

Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe | Full Text

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C

Polyacrylamide

From Wikipedia, the free encyclopedia 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]

Performance and Microbial Characteristics of Bioaugmentation Systems for Polyacrylamide Degradation | Journal of Polymers and the

Polyacrylamide (PAM) are water-soluble synthetic linear polymers made of either acrylamide or a combination of acrylamide and acrylic acid. PAM are widely used as water purification flocculants [ 2, 3 ], soil conditioning agents [ 4 ¨C 6 ], anticorrosives for irrigation furrows [ 7, 8 ], and in many biomedical applications [ 9 ].
