Novel montmorillonite composites including ionic liquid were prepared and utilized as coating materials for solid phase microextraction fibers. Ionic liquids containing amino terminated imidazolium cations with methyl and benzyl groups and hydrophobic anions (bis(trifluoromethylsulfonyl)imide) and hydrophilic anions (bromide and tetrafluoroborate) were intercalated to KSF-montmorillonite using stainless steel wire as support by using the layer-by-layer technique. After optimization of experimental conditions, solid phase microextraction (SPME) coupled to gas chromatography/mass spectrometry (SPME-GC/MS) after derivatization by silylation and high performance liquid chromatography/diode array detector (SPME-HPLC/DAD) were developed for the determination of 16 phenolic compounds. The developed SPME-GC/MS method had wider linearity and lower limit of detection than the developed SPME-HPLC/DAD method with similar repeatability (for 5 runs, less than 4.2 %) for a single fiber. The percentage of the variance between two different fibers was less than 6.0 % in both methods. The developed SPME methods were applied successfully to fresh fruit juices and the relative recoveries and the repeatabilities from spiked fruit juice samples were satisfactorily achieved. The results obtained with both chromatographic methods were in good agreement with each other.

制备了包含离子液体的新型蒙脱土复合材料，并将其用作固相微萃取纤维的涂层材料。使用不锈钢线作为载体，将含有甲基和苄基的氨基末端咪唑阳离子和疏水性阴离子（双（三氟甲基磺酰基）亚胺）和亲水性阴离子（溴化物和四氟硼酸根）的离子液体插入到KSF-蒙脱土中。技术。在优化实验条件之后，开发了用于甲硅烷基化衍生化后的固相微萃取（SPME）与气相色谱/质谱（SPME-GC / MS）和高效液相色谱/二极管阵列检测器（SPME-HPLC / DAD）。测定16种酚类化合物。与开发的SPME-HPLC / DAD方法相比，开发的SPME-GC / MS方法具有更宽的线性度和更低的检测下限，对于单根光纤具有相似的重复性（5次运行，小于4.2％）。在两种方法中，两种不同纤维之间的差异百分比均小于6.0％。所开发的SPME方法已成功地应用于新鲜果汁，并且令人满意地实现了加标果汁样品的相对回收率和可重复性。两种色谱方法获得的结果彼此吻合良好。所开发的SPME方法已成功地应用于新鲜果汁，并且令人满意地实现了加标果汁样品的相对回收率和可重复性。两种色谱方法获得的结果彼此吻合良好。所开发的SPME方法已成功地应用于新鲜果汁，并且令人满意地实现了加标果汁样品的相对回收率和可重复性。两种色谱方法获得的结果彼此吻合良好。
