  "abstract": "有机氯农药（OCPs）是典型持久性有机污染物，具有高毒性、生物蓄积性与难降解性，严重威胁生态环境与人体健康。复杂水体基质中痕量OCPs富集困难，商用吸附材料选择性有限，传统前处理有机溶剂消耗量大、富集效率偏低。本研究以毛玻璃片为载体，负载氯功能化共价有机骨架材料（Cl-COF），构建微固相萃取（μ-SPE）体系，用于水样中OCPs的高效富集。利用环加成反应在共价有机骨架上引入富含卤素的活性位点，结合红外光谱、X射线衍射、热重分析、X射线光电子能谱、孔结构分析及水接触角测试完成材料的系统表征。结果表明，氯官能化后修饰过程未破坏COF晶体骨架结构。Cl-COF热解温度提升至363 ℃，耐酸碱耐溶剂性优异，氯原子占比为9.77%，水接触角由99.54°升至127.10°，疏水性大幅提升。尽管比表面积与孔径略有下降，但仍保有充足吸附位点。疏水作用、卤键作用、π-π堆积作用协同驱动OCPs萃取富集。将Cl-COF用于涂层，与气相色谱-电子捕获检测器（GC-ECD）联用，建立μ-SPE-GC-ECD检测方法。该方法中5种OCPs目标物在各自线性范围内线性关系良好，检出限为0.20~0.42 ng/L，富集因子为891~1 308；兰州段黄河水和菜田浇灌水的加标回收率分别为89.2%~104.0%和89.0%~105.5%，相对标准偏差分别为1.7%~11.3%和2.4%~12.8%，具备良好的准确度、精密度与基质抗干扰能力。Cl-COF与玻片基底结合牢固，经30次吸附-解吸循环后萃取性能无明显衰减，稳定性与再生性能良好。相较于已报道检测方法，本方法综合萃取性能更佳，可为水环境中OCPs常态化监测提供技术支撑。",
