What environment the Anionic Polyacrylamide work in


Anionic Polyacrylamide environmental data:
1. Bioaccumulation
Anionic polyacrylamide is completely soluble in water , insoluble in solvents, there is a very low octanol / water partition coefficient (POE), for all practical purposes : log POW = 0 Therefore, the anionic polyacrylamide biological accumulation potential is zero.
2. Two non -biodegradable (degradation )
UV-sensitive anionic polyacrylamide , which broke the polymer backbone oligomers . Observed a positive correlation between the length and extent of exposition light ( i.e., reduction of molecular weight ) of collapse.
3 Biodegradable
Non- degradable anionic polyacrylamide has shown his stubborn microbial degradation . This may be related to a very high molecular weight , it is very difficult to microbial attack . However, once the polymer has been degraded by photolysis ( ie , the role of UV light ) , and macromolecular decomposed into oligomers, it becomes available,bio- mineralization. C14 labeled with a research to assess the potential of biodegradable anionic polyacrylamide proven combination of photolysis and microbial attack , resulting in natural attenuation of these polymers. 48 hours after exposure to ultraviolet light, oligomer MW <3, o0o daltons ) from 2% to 80 %. 38 days after the making of the incubation period of polymer degradation of at least 29 % oxygen and 17% anaerobic.
