Schneller Quecksilbernachweis: Ein Mikrosystem für die Flüssig‐flüssig‐Extraktion und den Nachweis von Quecksilberionen in Wasser nutzt eine ionische Flüssigkeit mit maßgeschneidertem fluorogenem Salz (L1) als extrahierende Flüssigphase. Das An‐ und Ausschaltverhalten senkt die Wahrscheinlichkeit falsch positiver Resultate und ermöglicht den Nachweis von 50 ppb Hg2+ in wässriger Lösung.
Quick test for quicksilver: A microdevice for liquid–liquid extraction and sensing of mercury ions in water uses an ionic liquid containing a task‐specific ionic fluorogenic salt (L1) as the extracting liquid phase. The “off–on” sensing response decreases the likelihood of false positives and allows detection of Hg2+ in aqueous solution down to 50 ppb.
