荧光纳米传感器设计是传感器发展的主要方向之一,本文从蜡烛燃烧灰烬中提取的碳量子点(CQDs)天然纳米颗粒组装出负载杯芳烃衍生物Zn2+配合物的荧光纳米传感器CQDs@L-Zn2+,实现了在纯水体系中对磷酸二氢根离子(H2PO?4)的选择性识别,检测不受其他各种无机、有机阴离子干扰,检测限达到4.85 mg L?1.
Fluorescent nanosensor design is one of the main directions for the development of sensors. In this paper, CQDs of natural quantum dots (CQDs) extracted from the burning ash of candles are assembled to form CQDs @ L-Zn2 + The selective recognition of dihydrogen phosphate ion (H2PO4) in pure water system was achieved. The detection limit was 4.85 mg L-1 without interference from other inorganic and organic anions.
