Fluorescent Sensing and Selective Pb(Ⅱ) Extraction by a Dansylamide Ion-Exchanger

摘要

It has been demonstrated that a simple (bis)-dansylamide ion-exchanger selectively extracts Pb(Ⅱ) from water into DCE, with concurrent fluorescence quenching. We are planning extensive structural and spectroscopic studies with 1 and analogous chelates, as well as application of the ion-exchange extraction methodology for rapid screening of potential extractants and sensors for Pb(Ⅱ) and other toxic metals.
