摘要： 鉴于消防员灭火防护服中典型PFASs污染物的持久性、强生物积累性及其高昂的检测费用，以2-氨基对苯二甲酸为有机配体、二氯二茂锆为金属源，将具有pH响应的荧光染料RGH通过原位包封策略封装到具有活性氨基的锆基金属有机笼NH2-Zr-MOC中，制备具有化学稳定性好、荧光量子产率高的双发射RGH-NH2-Zr-MOC荧光传感器，借助其与PFOA、PFOS之间的强氢键和静电作用，实现对PFOA、PFOS污染物的高灵敏检测。研究表明，该荧光传感器对PFOA和PFOS的检出限分别可达20.7 nmol/L和12.9 nmol/L（S/N=3）。进一步借助254 nm紫外灯照射和RGB数值分析法，实现对消防员灭火防护服PFASs（均按PFOS的百分含量折算）的可视化定量检测，其准确性与高效液相色谱-质谱法相当，且成本极低，为消防员的职业暴露防护提供了一种简便实用的现场快速检测技术。

Abstract: Given the persistence, bioaccumulation and high testing costs of typical PFASs contaminants in the firefighters' turnout gear, 2-amino-terephthalic acid served as ligand and zirconium dichloride as metal source, then the fluorescent dye RGH with pH response was encapsulated into zirconium organic cage NH2-Zr-MOC with active amino group by the strategy of in-situ encapsulation, and the double-emission fluorescence sensor RGH-NH2-Zr-MOC with good chemical stability and high fluorescence quantum yield was fabricated. With the help of strong hydrogen bond and electrostatic interactions between PFOA, PFOS and fluorescence sensor, the highly sensitive detection of PFOA and PFOS contaminants was realized. The results showed that the fluorescence sensor had high sensitivity to PFOA and PFOS and strong anti-interference capability, and the detection limits can reach 20.7 nmol/L and 12.9 nmol/L, respectively (S/N=3). Further, with the help of ultraviolet light irradiation with 254 nm and RGB numerical analysis method, the visually quantitative detection of PFASs (all converted as the percentage of PFOS) for firefighting protective clothing was realized. The accuracy of this method was comparable to that of HPLC-MS/MS, and the cost was very low. It provides a simple and practically rapid detection technology for firefighters' occupational exposure protection.
