Covalent organic framework (COF)-TpBD was grafted on the arrayed nanopores of stainless steel fiber (SSF) with (3-aminopropyl) triethoxysilane as the cross-linking agent. The prepared SSF bonded with COF-TpBD showed high thermal and chemical stability and excellent repeatability. The prepared SSF bonded with COF-TpBD was also used for the solid-phase microextraction (SPME) of seven kinds of polycyclic aromatic hydrocarbons (PAHs) in actual water samples, followed by gas chromatography with flame ionization detection (GC-FID) determination, which exhibited low limits of detection (LODs), good relative standard deviation (RSD) and high recoveries.
共价有机框架（COF）-TpBD 接枝在不锈钢纤维（SSF）的阵列纳米孔上，（3-氨丙基）三乙氧基硅烷作为交联剂。制备的 SSF 与 COF-TpBD 键合后表现出高热稳定性和化学稳定性以及优异的可重复性。制备的 SSF 与 COF-TpBD 键合后还用于实际水样中七种多环芳烃（PAHs）的固相微萃取（SPME），然后用火焰离子化检测（GC-FID）气相色谱法测定，其检测限（LOD）低，相对标准偏差（RSD）好，回收率高。
