摘要

报道了一种高选择性的双光学传感器，用于100%水介质中的氟化物检测，利用荧光素的Al3+络合物。该传感器表现出明显的比色和荧光响应，达到0.7 ppm（紫外-可见）和40 ppb（荧光）的检测限。该方法在水样和纤维素纸条上得到验证，为常规氟化物监测提供了一种实用、低成本的方法。

A fluorescein based dual optical sensor for highly selective and sensitive fluoride detection in 100% water medium†

A highly selective dual optical sensor for fluoride detection in 100% aqueous medium is reported, utilizing an Al³⁺-complex of fluorescein. The sensor exhibits distinct colorimetric and fluorometric responses, achieving detection limits of 0.7 ppm (UV-Vis) and 40 ppb (fluorescence). This method, validated on water samples and cellulose paper strips, offers a practical, low-cost approach for routine fluoride monitoring.
