Preparation method of organic-inorganic hybrid material and application of organic-inorganic hybrid material in removing plant pigment

The invention discloses preparation of an organic-inorganic hybrid material and application of the organic-inorganic hybrid material to removal of plant pigment. The organic-inorganic hybrid material is prepared from the following raw materials: an organic ligand 5 '-(4-carboxyl phenyl)-2', 4 ', 6'-trimethyl-[1, 1 ': 3', 1 '-terphenyl]-4, 4'-dicarboxylic acid and aluminum nitrate nonahydrate Al (NO3) 3.9 H2O; the mass ratio of the two is (4-5): 6; the solvent comprises acetic acid and N, N-dimethylformamide (DMF); the volume ratio of the two is (1-1.5): 5; the preparation method comprises the following steps: fully mixing the raw materials with a solvent, carrying out solvothermal reaction, washing, depositing and drying to obtain the organic-inorganic hybrid material. The organic-inorganic hybrid material is used for adsorbing and removing pigments in an object to be detected, and then pesticide residue detection is carried out. The method has the advantages of simple operation, good stability, excellent ads
