The removal of toxic phenolic compounds from wastewater streams with ionic liquids as extracting agents have been addressed with experiments and simulations. Three phenolic compounds, phenol, chlorophenol and o-cresol, were extracted from aqueous streams at different concentrations using five ionic liquids allowing to study the effect of both ionic structures, the anion and the cation, on the extraction efficiency. Besides, the interactions between phenols and ions were analysed by means of atomistic molecular dynamic simulations and their solvation environment described. Finally, the accomplishment of the regulations regarding phenol concentrations in wastewater streams was discussed.
