Synthesis method of UiO-66/HOCN material and application of UiO-66/HOCN material in detection of pesticide residues in tea leaves

The invention belongs to the field of preparation of nanomaterials, and particularly relates to a synthesis method of a UiO-66/HOCN material and application of the UiO-66/HOCN material in detection ofpesticide residues in tea leaves. The material is based on a complex of a metal organic framework compound and a two-dimensional conjugated carbon-nitrogen nanomaterial. Pesticide residues in a tea sample are enriched through an SPME coating method for preparing a UiO-66/HOCN material through an in-situ thermal polymerization method, and then detection via GC-MS (gas chromatography-mass spectrum)is carried out. The synthesized UiO-66/HOCN material is good in thermal stability, rich in active sites, large in specific surface area, small in the required amount of UiO-66/HOCN material samples,good in reproducibility and long in service life, and the established method can be used for simultaneously determining various pesticide residues in a complex matrix. 本发明属于纳米材料制备领域，具体涉及一种UiO-66/HOCN材料的合成方法及其在茶叶残留农药检测中的应用。该材料基于
