Polycyclic Aromatic Hydrocarbons (PAHs) are pollutants of concern with potential adverse health impacts. The very low solubility of PAHs in water derails the possibility of using microorganisms to biodegrade them. In the present work, different Ionic Liquids (ILs) possessing surface active properties have been selected to shed light on the implementation of a true remediation strategy. An outstanding enhancement of solubility for phenanthrene (used as a model PAHs) was found by [IM12]+ cation when is combined with docecylbenzosulfonate anion [DDBS]. The ammonium-based ILs [N1182OH][Cl] have been satisfactorily able to solubilize aromatic compounds by means of mixture strategies. A complete metabolization for this cation was detected in less than 10 days classifying it as a readily biodegradable compound. The metabolic pathway was also reported.

摘要

Polycyclic Aromatic Hydrocarbons (PAHs) are pollutants of concern with potential adverse health impacts. The very low solubility of PAHs in water derails the possibility of using microorganisms to biodegrade them. In the present work, different Ionic Liquids (ILs) possessing surface active properties have been selected to shed light on the implementation of a true remediation strategy. An outstanding enhancement of solubility for phenanthrene (used as a model PAHs) was found by [IM12]+ cation when is combined with docecylbenzosulfonate anion [DDBS]. The ammonium-based ILs [N1182OH][Cl] have been satisfactorily able to solubilize aromatic compounds by means of mixture strategies. A complete metabolization for this cation was detected in less than 10 days classifying it as a readily biodegradable compound. The metabolic pathway was also reported.
