Does enhanced oil recovery polymer promote microbial growth and accelerated corrosion?

Jia, Ru., Yang, D., Rahman, H. B. A., & Tingyue, Gu. (2018). An enhanced oil recovery polymer promoted microbial growth and accelerated microbiologically influenced corrosion against carbon steel.

Are polyacrylamide-degrading bacterial strains isolated from soil?

Two polyacrylamide-degrading bacterial strains were isolated from soil, Bacillus sphaericus and Acinetobacter sp., utilizing 16–19% polyacrylamide after 14 days of cultivation (Matsuoka et al., 2002).

How is partially hydrolyzed polyacrylamide wastewater treated?

Yongrui, Pi., Zheng, Z., Bao, M., Li, Y., Zhou, Y., & Sang, G. (2015). Treatment of partially hydrolyzed polyacrylamide wastewater by combined fenton oxidation and anaerobic biological processes.

Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?

PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2022; Liu et al., 2016; Xiong et al., 2018).

Is polyacrylamide soluble in water?

Polyacrylamide (PAM) is a synthetic polymer of long-chain acrylamide subunits, high molecular weight (1000 to 20 × 10 6 g/mol), and a wide range degree of hydrolysis (Abidin et al., 2012; Joshi & Abed, 2017). It is extremely soluble in water, but not soluble in organic solvents, such as methanol and hydrocarbons (Lu & Wu, 2002; Braun et al., 2022).

Where does acrylamide come from?

According to the Environmental Health Criteria (EHC) number 49 of acrylamide, published in 1985 by the World Health Organization (WHO), the source of acrylamide in the environment is mainly released from polyacrylamide usage (Filippini, 1986).
