基于香豆素类荧光探针可视化检测食品中氰化物
Visual detection of cyanide in food based on coumarin fluorescent probe
摘要
Abstract
[Objective]To develop a method for detecting cyanide in food based on a novel fluorescent probe.[Methods]Based on the strong nucleophilicity of cyanide,a novel reactive coumarin fluorescent probe is synthesized.The response mechanism,reaction rate,selectivity,and linear relationship between the probe and cyanide are analyzed and validated using real samples.[Results]The probe has excellent selectivity for cyanide and demonstrates a rapid response to cyanide,able to complete the reaction within 1 minute.At a probe concentration of 10 µmol/L,the linear range of cyanide detection is 5~90 µmol/L,with a linear equation of Y=11.645 45+7.014 55X and a detection limit of 0.065 µmol/L.In actual sample testing,the recovery rate of spiked samples is 97.9%~105.0%.[Conclusion]This probe can quickly and accurately detect cyanide.关键词
