Ecotoxicity evaluation towards Vibrio fischeri of imidazolium- and pyridinium-based ionic liquids for their use in separation processes

Abstract

Estudio de la toxicidad de 24 líquidos iónicos mediante el test de inhibición con la bacteria Vibrio fischeri.

The present work reports the toxicity of 24 imidazolium- and pyridinium-based ionic liquids through Vibrio fischeri inhibition basic test. The toxicity-structure relationship of the ionic liquids has been studied through the anion and cation core, the cation alkyl chain length, and the presence of functional groups on the cation alkyl chain. y. Finally, considering ionic liquids as potential solvents for the aromatic/aliphatic separation process, their toxicity has been compared to that of sulfolane, which is the current organic solvent used in this kind of process.
