Abstract The green glycine ionic liquid functionalized β-cyclodextrin polymer material (AAIL-β-CDCP) was synthesized and characterized with Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM). A novel method of solid phase extraction (SPE) coupled with high-performance liquid chromatography (HPLC) for separaton/detection of pyrethroids (permethrin and fenpropathrin) was established. Pyrethroids were rapidly adsorbed on AAIL-β-CDCP and desorbed with methanol. Under the optimized conditions, The linear ranges of permethrin and fenpropathrin were 0.025–20.00 µg mL−1 and 0.03–25.00 µg mL−1, the limits of detection (LOD) of permethrin and fenpropathrin were 0.020 µg mL−1 and 0.023 µg mL−1, the pre-enrichment ratios of permethrin and fenpropathrin were 12.0 and 14.0 (solution volume/elution volume before extraction), respectively . AAIL-β-CDCP could be used repeatedly for 10 times. The adsorption mechanism of permethrin and fenpropathrin on AAIL-β-CDCP was studied with the kinetic model and the interaction of AAIL-β-CDCP and pyrethroids. This proposed method had been successfully applied to the detection of pyrethroids in tea and tomato samples with the recovery was 92.0–100.6% and the RSD was 2.1–4.2%. Graphical Abstract

摘要 合成了绿色甘氨酸离子液体功能化β-环糊精聚合物材料（AAIL-β-CDCP），并采用傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）对其进行表征。建立了一种新的固相萃取 (SPE) 结合高效液相色谱 (HPLC) 分离/检测拟除虫菊酯 (氯菊酯和甲氰菊酯) 的方法。拟除虫菊酯迅速吸附在 AAIL-β-CDCP 上并用甲醇解吸。在优化条件下，氯菊酯和甲氰菊酯的线性范围分别为0.025-20.00 µg mL-1和0.03-25.00 µg mL-1，氯菊酯和甲氰菊酯的检出限（LOD）分别为0.020 µg mL-1和0.023 µg mL-1 -1，氯菊酯和甲氰菊酯的预富集比分别为12.0和14.0（提取前溶液体积/洗脱体积），分别 。AAIL-β-CDCP可重复使用10次。通过动力学模型和AAIL-β-CDCP与拟除虫菊酯的相互作用研究了氯菊酯和甲氰菊酯对AAIL-β-CDCP的吸附机理。该方法已成功应用于茶叶和番茄样品中拟除虫菊酯的检测，回收率为92.0-100.6%，RSD为2.1-4.2%。图形概要
