  • Biodegradation for hydrolyzed polyacrylamide in

    2015-11-1 · Anionic polyacrylamide is a negatively charged high molecular weight polymer and strongly resists biodegradation (Suzuki et al., 1978). This is due to its high molecular weight (2.2 × 10 7 g/mol), but also the molecular structure of the HPAM “backbone” linkage (Chang et al., 2001).

    2019-4-1 · Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes. The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties.
