photochemical fate of nonionic polyacrylamide induced

the present study explored the photochemical fate of nonionic pam (npam, the fundamental type of diverse pams) under uv irradiation by using h 2 o 2 as a radical precursor.

polyacrylamide pam flocculants water treatment industrial use,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.

the thermal gelation behavior and performance evaluation of sale

a delayed crosslinked polymer gel was developed for in-depth water control in mature oilfields. the thermal gelation behavior of nonionic polyacrylamide (npam) and pei was investigated, and sodium citrate (nacit) was selected as a new retarder to prolong the gelation time.

adsorption of different ionic types of polyacrylamide on,the polymers investigated were nonionic polyacrylamide (npam), anionic polyacrylamide (apam) and cationic polyacrylamide (cpam). this is because polyacrylamide-based polymers are commonly used in various water treatment industries [ 9 , 31 , 32 , 33 , 34 ].

molecular dynamics-assisted design of high temperature

the so-called poloxamer is a new type of polymer nonionic polyol with low toxicity, low irritation, and good biocompatibility, which can be used in biological fields such as pharmaceutical excipients, gene therapy, and the inhibition of postoperative intestinal adhesions [22,23,24].

Does anionic polyacrylamide biodegrade?
ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
Is nionic polyacrylamide a hazard?
nionic polyacrylamide.NICNAS has assessed anionic polyacrylamide in an IMAP Tier 1 assessment and considers it a po ymer of low concern1 . In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the envi
Is polyacrylamide a cationic or nonionic polymer?
Degradable or bioaccumulative. Anionic polyacrylamide has low acute toxicity. Co-chemical properties Polyacrylamide polymers can exist in cationic, anionic or nonionic forms, depending on their ionic charge. Nonionic forms of polyacrylamide are generated from basic polymers.
Is anionic Polyacrylamide a chemical of low concern?
In addition, based on the assessment of environmental hazards, NICNAS has also identified anionic polyacrylamide as a chemical of low concern to the environment. Chemicals of low concern are unlikely to have adverse effects on the environment if released into the environment from the production process.
