摘要(Abstract)：

针对管内固相微萃取技术中普通整体柱比表面积小、结合位点少和作用效率不高的问题，基于有机金属框架柱后衍生原位生长技术，制备比表面积大、金属位点多的沸石咪唑酯骨架ZIF-8修饰整体柱，对整体柱的结构及性能进行表征，并将其与高效液相色谱-二极管阵列检测技术联用，进行花蛤和贻贝中软骨藻酸的在线富集及检测分析。结果表明：ZIF-8修饰整体柱的聚合结构紧密均匀，比表面积为230.92 m2/g;花蛤和贻贝的贝肉样品中软骨藻酸的检测限达到0.3μg/kg,花蛤和贻贝中软骨藻酸的加标回收率分别达到(92.4±2.5)%～(94.5±1.0)%、(91.4±2.4)%～(92.6±1.5)%。
