摘　　要：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 carbon quantum dots have been efficiently prepared and isolated from a common carbon source, candle soot. And then, driven by the need to detect trace amounts of H2PO4^- in water, a highly selective and ultrasensitive calix[4]arene-derivative modified carbon nanosensor CQDs@L-Zn^2＋ has been assembled for H2PO4^- recognition at the 4.85 mg L^-1 level from aqueous solution, with excellent discrimination against other organic and inorganic anions.
