polyelectrolyte polymers—types, forms, and function

in the simplest sense, water-soluble polyelectrolytes are polymers that contain charged disassociating monomer subunits. the charges can be pendant to the polymer chain or be part of the polymer chain itself. the overall charge of the polymer chain can be neutral (nonionic), positive (cationic), or negative (anionic).

understanding the interaction of polyelectrolyte,a recent study 208 of the adsorption of human serum albumin on a spherical polyelectrolyte brush by itc has revealed that the free energy of binding depends very little on the temperature, while the enthalpy and the entropy of adsorption vary linearly with temperature (figure 10 c). 208 figure 10 b,c suggests that the strong enthalpy–entropy

the above facts may lead to the efficiency of aops is greatly reduced so that directly abandoned by front-line engineers. therefore, it seems not a wise idea to give up free radicals with high oxidative capacity. essentially, the reason for the decreased activity of free radicals in high-salinity organic wastewater is the influence of the

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.

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.
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.
Are polyacrylates recalcitrant to degradation?
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. Polyacrylamide may be degraded to acrylamide anaerobically, but not aerobically.
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.
