How do you get rid of phenolic compounds?
How do you get rid of phenolic compounds?
Many phenolic compounds can be removed efficiently by conventional treatments such as extraction, distillation, chemical oxidation, electrochemical oxidation and adsorption among others.
What are phenolic compounds examples?
Classification of Phenolic Compounds
| Polyphenolic Compounds | Example |
|---|---|
| Phenolic acids | Hydroxycinnamic acids Caffeic acid Chlorogenic acid Ferulic acid Sinapic acid Caftaric acids Neochlorogenic acid p-Coumaric acid |
| Hydroxybenzoic acids Ellagic acid Gallic acid | |
| Flavonoids | Flavonols Myricetin Quercetin Kaempferol Isorhamnetin |
What is the significance of phenol degrading bacteria?
Phenol is a ubiquitous organic contaminant in drinking water. Biodegradation plays an important role in the elimination of phenol pollution in the environment, but the information about phenol removal by drinking water biofilters is still lacking.
Does phenol degrade over time?
Phenol is degraded rapidly in air by gas-phase hydroxyl radical reaction (estimated half-life 14.6 hours), but may persist in water for a somewhat longer period.
How do you destroy phenol?
The most important membrane technologies used to remove phenols from wastewater are extractive membrane bioreactors and hollow fiber membranes; photocatalytic membrane reactors; high-pressure membrane processes such as nanofiltration, reverse osmosis, and pervaporation; and membrane distillation [3, 9, 24].
Does phenol decompose?
Phenol and particularly the phenoxy radical play a key role as intermediates in the oxidation of benzene. The decomposition products of phenol and phenoxy radical, C5H6 and C5H5, are essential building blocks of larger aromatic species such as indene and naphthalene,3–7 precursors of soot and particulate matter.
Can phenol be oxidized?
Phenols are rather easily oxidized despite the absence of a hydrogen atom on the hydroxyl bearing carbon. Among the colored products from the oxidation of phenol by chromic acid is the dicarbonyl compound para-benzoquinone (also known as 1,4-benzoquinone or simply quinone); an ortho isomer is also known.
What is phenol used for in microbiology?
Phenol and phenolic compounds have been used to control microbial growth. (a) Chemical structure of phenol, also known as carbolic acid. (b) o-Phenylphenol, a type of phenolic, has been used as a disinfectant as well as to control bacterial and fungal growth on harvested citrus fruits.
