Cationic polyacrylamide copolymers (PAMs): environmental half life

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.

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.

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting

Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.

Microbial degradation of polyacrylamide and the

Abstract Polyacrylamides are widely applied for instance in wastewater treatment, papermaking, oil recovery and mining. Since they are bulk chemicals used in large quantities around the world, their fate in nature is of considerable interest. Both single microbial species as well as mixed populations have been investigated for degradation.

Hydrolyzed polyacrylamide biodegradation and mechanism in sequencing

The combination of aerobic biodegradation and the addition of a biofilm carrier can provide a new approach to the degradation process. Many researchers tend to use isolated microorganisms in pure cultures or other co-metabolism substrates to degrade HPAMs (Stahl et al., 2000).
