What is your problem?? Usually the extraction of phenols on this type of water develop an usual color in the extract
in the other hand phenols and benzene had a common functional group; what is your analysis technique?? GC, LC, spectrophotometric??
Dear Hilda: I am looking to treat refinery wastewater with high benzene and phenol content. Rather than other destructive mechanisms, I am evaluating the cost of recovering these compounds for simplicity.
Juzer, I suspect that there are many published studies regarding the sorption of benzene and phenolics to materials such as activated carbon and organic matter. Although that is not a liquid/liquid removal, it is non-destructive.
Pervaporation is a promising technology for the removal of volatile organic compounds (VOCs) from industrial wastewaters, including petroleum-based solvents such as phenols and benzene. It might constitute an economical alternative to the solvent extraction technology being considered.
Hydrophobic resin adsorption is also an option. For example, take a look at http://www.deswater.com/DWT_abstracts/vol_73/73_2017_348.pdf.
