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. Biodegradation of

Polyacrylamide degradation and its implications The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
Polyacrylamide Degradation in Soil and Water PAM degradation rates in soil are estimated to be approximately 10% year-1 (Barvenik, 1994). Degradation of the acrylamide monomer (AMD) is fairly rapid. AMD was completely degraded within 5 days
Microbial degradation of polyacrylamide and the deamination product polyacrylate - ScienceDirect
The analysis of the polyacrylamide and its degradation products by SEC showed that the molecular weight of the polyacrylamide had reduced from 2000 to 500 kDa during the E. agglomerans cultivation. However, two commercial brands were tested as
Polyacrylamide Knowledge 1. What is polyacrylamide PAM? Polyacrylamide is a polymer (-CH2CHCONH2-) formed from acrylamide subunits, it is long-chain polymer (same molecule repeating itself many times) designed to attract either positively

fresh water by bacteria with a half-life of 55-70 h, after acclimatization for 33-50 h [41]. Acrylamide has been shown to remain slightly longer in estuarine or salt than fresh water [15]. Acrylamide releases to land and water from 1987 to 1993
However, cross-linked variants of polyacrylamide have shown greater resistance to all of these methods of degradation, and have proved much more stable. Environmental effects Concerns have been raised that polyacrylamide used in agriculture may
high molecular polyacrylamide pam flocculant
Polyacrylamide degradation and its implications 2025-09-07· High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as
This review focuses on the mechanisms of transfer and degradation, which can affect both PAM and residual AMD, with a special attention given to the potential release of AMD during PAM degradation. Due to the ability of PAM to adsorb onto
