Fluorinated Ionic Liquids – A Relevant PFAS Class?
Thomas Knepper, Isabelle Neuwald and Daniel Zahn (Hochschule Fresenius, University of Applied Sciences)
Are (fluorinated) ionic liquids relevant environmental contaminants? This question is aimed to be answered by i) giving an overview regarding marketed and patented ionic liquids( ILs), ii) introducing some state-of-the-art analytical techniques, such as e.g. fragmentation flagging, a high-resolution mass spectrometric screening variant that utilizes intentionally produced indicative in-source fragments of per- and polyfluoroalkyl substances, iii) recent findings of ILs in environmental water samples and iv) finally address the relevance of ILs in the context of persistent, mobile, and toxic chemicals, in perspective of both, scientific and regulatory interest.
