摘要

Based on the thioether-rich crown receptor, we describe a naphthalimide based bifunctional fluorescent sensor (FS-G) for simultaneous detection and separation of trace Hg2+ in water. FS-G exhibited excellent selectivity toward Hg2+ in aqueous environment and showed 5-fold increase in fluorescence emission intensity upon the addition of Hg2+. A good linearity was observed between the fluorescence enhancement and the dose of Hg2+ with a lower detection limit of 33.4 ppb. Additionally, adsorption capacity of FS-G is 7.4 mg g-1. FS-G can be easily regenerated when treated with dimercaptosuccinic acid. These results indicate that FS-G has potential applications for detection and removal of trace Hg2+ in water.
