Core-shell polyaniline/polyacrylonitrile nanofibers mat (PANI/Pan NFsM) was prepared for extraction of hydrophilic non-steroidal anti-inflammatory drugs (NSAIDs) in environmental water. Superior adsorption and desorption performance of PANI/Pan NFsM was confirmed by both static and dynamic adsorption/desorption experiments. These properties proved PANI/Pan NFsM was a potentially efficient and fast solid phase extraction (SPE) adsorbent for NSAIDs. Under the optimized conditions, only 3 mg of PANI/Pan NFsM could easily extract eight target analytes in 10 mL of water sample without any pre-treatment, and the analytes retained on NFsM could be easily eluted by 500 μL of 1% acetic acid methanol for direct UPLC-MS/MS analysis. In addition, each piece of PANI/Pan NFsM could be reused for at least 20 times without performance decline. Possible adsorption mechanisms were also proposed. Practical feasibility was validated through the actual sample analysis.
核壳型聚苯胺/聚丙烯腈纳米纤维垫（PANI/Pan NFsM）被制备用于从环境水中萃取亲水性非甾体抗炎药（NSAIDs）。通过静态和动态吸附/解吸实验证实了 PANI/Pan NFsM 具有优越的吸附和解吸性能。这些特性证明 PANI/Pan NFsM 是一种潜在的高效、快速固相萃取（SPE）吸附剂，可用于 NSAIDs。在优化条件下，仅需 3mg 的 PANI/Pan NFsM 即可在无需任何预处理的情况下从 10mL 水样中轻松提取 8 种目标分析物，而保留在 NFsM 上的分析物可以很容易地用 500μL 1%乙酸甲醇洗脱，直接用于 UPLC-MS/MS 分析。此外，每片 PANI/Pan NFsM 可以至少重复使用 20 次而不会性能下降。还提出了可能的吸附机制。通过实际样品分析验证了实际可行性。
