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 defines...

assessment of polyacrylamide degradation using advanced oxidation

ASSESSMENT OF POLYACRYLAMIDE DEGRADATION USING ADVANCED OXIDATION

The degradation of these polymers using Fenton reagent, H 2 O 2 /UV, Fe 2+ /H 2 O 2 /UV, and Fe 3+ /H 2 O 2 /UV, as well as ferrate (VI), showed that PAM may present different behaviors under oxidation processes, especially regarding their ionic charge.

Chemical degradation of polyacrylamide by advanced oxidation processes

The addition of tartrate had a positive effect on chemical oxygen demand (COD) removal and increasing the concentrations of reagents promoted the oxidation of PAM by the UV/Fenton/C4H4O process. This paper presents the results obtained from the oxidation of polyacrylamide (PAM) by the UV/H2O2, Fenton, UV/Fenton, visible light/Fenton, visible light/Fenton/C2O , UV/Fenton/C2O , visible light ...

microbial degradation of polyacrylamide and the deamination product

Microbial degradation of polyacrylamide and the deamination product

Polyacrylamide may be degraded to acrylamide anaerobically, but not aerobically. 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.
