synthesis and characterization of acrylamide‐based anionic
an assessment of the anionic charge on reduced viscosity and molecular weight showed decrease in reduced viscosity and m w would occur with an increase in weight portion of amps monomer in the feed. this effect may be attributed to the repulsive effects in the amps monomer which is an inherent polyacrylamide flocculant in anionic polymers.
zimbabwe polyacrylamide market price flocculant powder,zimbabwe polyacrylamide market is expected to grow during 2024-2030.polyacrylamide is a kind of water soluble polymer, has unique effect to increase the viscosity of water or to promote the flocculation of particles present in water, it can also reduce the frictional resistance between the liquid.
acrylamide‐based anionic polyelectrolytes and their
water-soluble polymers are found in a very broad range of industrial applications. an important class of these is acrylamide-based polymers which bear negative charges along the polymer chain and are called anionic polyelectrolytes. these negatively charged polymers are widely used as flocculants, rheology control agents, and adhesives.
synthesis, properties and performance of organic polymers,the majority of commercial anionic flocculants contain carboxylate and sulfonate ions as the anionic functional group, and this can range from 1 to 100% of the monomer units. 10 anionic polymers are most commonly used as flocculants in mineral processing applications. 1,3 optimal flocculation is possible due to strong ionic interaction between
acute and long-term effects of anionic polyacrylamide apam
the application of synthetic polymers such as anionic polyacrylamide (apam) in enhanced oil recovery (eor) may increase in the future. this can lead to environmental release through offshore produced water discharges with so far limited knowledge on impacts in marine ecosystems. we investigated impacts of apam polymers on two marine copepod

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.
binding of anionic polyacrylamide with amidase and laccase,amidase and laccase play a key role in the degradation process of anionic polyacrylamide (hpam). however, the largest challenge of hpam enzymatic degradation is whether the enzyme can bind with a substrate for a period of time. here, the most suitable complexes, namely, rh amidase-hpam-2 and bacillus subtilis (b. subtilis) laccase-hpam-3, were obtained by docking, and they were carried out for

acceleration of the biodegradation of cationic polyacrylamide
as a flocculant of sewage sludge, cationic polyacrylamide (cpam) enters the environment with sludge and exists for a long time, posing serious threats to the environment. due to the environmental friendliness and high efficiency in the process of organic solid waste treatment, hyperthermophilic composting (htc) has received increasing attention.

- How is polyacrylamide biodegraded?
- Both single microbial species as well as mixed populations have been investigated for degradation. 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.
- How are polyacrylamides deaminated to polyacrylates?
- Polyacrylamides are first deaminated to polyacrylates by microbial amidases. Remaining polyacrylates are more recalcitrant to degradation. Polyacrylamide degradation has mainly been reported for aerobic bacteria. With fungi the degradation is initiated by secreted lignin degrading oxidases.
- Is polyacrylate more recalcitrant to biodegradation than amide?
- The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties. There are nevertheless reports on microbial growth with polyacrylamide and polyacrylate as the carbon sources.
- Can polyacrylamide be degraded in fungi?
- Polyacrylamide degradation has mainly been reported for aerobic bacteria. With fungi the degradation is initiated by secreted lignin degrading oxidases. Polyacrylamide may be degraded to acrylamide anaerobically, but not aerobically. Polyacrylamides are widely applied for instance in wastewater treatment, papermaking, oil recovery and mining.
