Polyacrylamide degradation and its implications in environmental systems | npj Clean Water - Nature

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...

Effects of physicochemical properties of polyacrylamide (PAA) and (polydimethylsiloxane) PDMS on cardiac cell behavior - Soft

Polyacrylamide [IUPAC poly(2-propenamide), hereafter PAM] is a polymer (¨CCH 2 CHCONH 2 ¨C) formed from acrylamide subunits. Polyacrylamide with only acrylamide monomers is nonionic; other monomers such as acrylate or 2-acrylamido-2-methylpropane sulfonate (AMPS) can be copolymerized at various percentages to form anionic PAM.

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Preparation of polyacrylamide with high relative molecular weight based on miniemulsion polymerization | 2021 3rd International Conference on

Polyacrylamide (PAM) and its derivatives are multifunctional water-soluble polymers, which can be divided into three types: nonionic, cationic and anionic. Polyacrylamide (PAM) with high molecular weight was synthesized by microemulsion method.

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes

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 PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown

effect of hydrolyzed polyacrylamide on oil droplet stability in polymer-flooding produced water: variation of oil droplets diameter and oil

Effect of hydrolyzed polyacrylamide on oil droplet stability in polymer-flooding produced water: variation of oil droplets diameter and oil

Hydrolyzed polyacrylamide (HPAM) in polymer flooding leads to stable oil-in-water emulsions, making the oil removal from polymer-flooding produced water (PFPW) more difficult. To elucidate HPAM¡¯s effects on the oil separation performance of conventional physical separation process for PFPW, the stability, and diameter of oil droplets of simulated PFPW were accurately determined using the

Biodegradation of partially hydrolyzed polyacrylamide by immobilized bacteria isolated from HPAM-containing wastewater - American Institute

The special function bacteria R2 was screened from hydrolyzed polyacrylamide (HPAM)-containing wastewater that could use HPAM as the sole carbon source and nitrogen source. Through optimizing the condition of HPAM biodegradation, the removal rate of R2 free strain reached to 41.6% when pH was 7, temperature was 35¡ãC, inoculation quantity (v/v) was 3% and activation time was 4.
