In this thesis, a new nanocomposite UiO-66-NH2/Glycine/GO based on the metal-organic framework was synthesized and used as an adsorbent for solid phase microextraction. Pesticide chlorpyrifos was selected as a model compound for this extraction. Corona discharge ionization-ion mobility spectrometry (CD-IMS) was applied as an identification system. At the first, the functionalized organic metal framework was synthesized using 2-aminoterephthalic acid as an organic ligand and ZrCl4 salt under hydrothermal conditions. Subsequently, graphene oxide was synthesized by Hummer method and glycine was used as a linker between metal organic framework and graphene oxide. x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA), fourier-transform infrared (FT-IR), and energy-dispersive x-ray (EDX) were used for characterization of the structure and morphology of the compounds. In order to increase the extraction efficiency and preconcentration of the analyte, extraction temperature and extraction time were examined. In this method, analysis factors were achieved as follow: limit of detection; 0.15 µg.L-1, limit of quantification 0.5 µg.L-1, linear dynamic range; 0.5-20.0 µg.L-1 and correlation coefficient; 0.9992.
