In this study, we evaluated the performance of a novel tetrafluoroterephthalonitrile-crosslinked β-cyclodextrin polymer (TFN-CDP) as a solid-phase extraction (SPE) material for the recovery of up to 189 diverse organic micropollutants (MPs) from water. The optimized extraction procedure requires loading of water samples adjusted to a pH of 3 onto 500 mg of TFN-CDP packed into an SPE cartridge. Under these conditions, 88.7% of the MPs have average extraction efficiencies greater than 80%. The optimized recovery procedure requires elution with 15 mL of methanol amended with 15 mg of calcium chloride. Under these conditions, 58.4% of the MPs have average absolute recoveries between 80% and 120%. We compared the performance of the optimized SPE method for TFN-CDP with a previously optimized SPE method employing hydrophilic-lipophilic balance (HLB) adsorbents in nanopure water and in wastewater-impacted surface water. The data indicate that the optimized TFN-CDP method performs as well as or better than the optimized HLB-based SPE method. These findings represent an important step forward in the development of sustainable and inexpensive materials for the extraction and recovery of organic MPs from water.

在这项研究中，我们评估了新型四氟对苯二甲腈交联的β-环糊精聚合物（TFN-CDP）作为固相萃取（SPE）材料从水中回收多达189种不同有机微污染物（MPs）的性能。优化的提取程序需要将已调至3的pH的水样品上样至装在SPE小柱中的500 mg TFN-CDP。在这些条件下，88.7％的MP的平均提取效率大于80％。优化的回收程序需要用15 mL甲醇和15 mg氯化钙修正的洗脱液。在这些条件下，58.4％的国会议员的平均绝对回收率在80％至120％之间。我们将针对TFN-CDP的优化SPE方法的性能与先前在纳米纯水和受废水影响的地表水中采用亲水-亲脂平衡（HLB）吸附剂的SPE方法进行了优化。数据表明，优化的TFN-CDP方法的性能与优化的基于HLB的SPE方法相同或更好。这些发现代表了开发可持续且廉价的材料以从水中提取和回收有机MP的重要一步。
