Synthesis method of MOFs composite material and application of MOFs composite material in glyphosate detection

The invention provides a synthesis method of an MOFs composite material and application of the MOFs composite material in glyphosate detection, and belongs to the technical field of chemical analysis and detection. The synthesis method of the MOFs composite material comprises the following steps: S1, stirring imidazole-2-formaldehyde, zinc acetate dihydrate and zinc porphyrin at normal temperature for synthesis to prepare the MOFs composite material which is expressed as ZnTCPP (at) ZIF-90. The method for detecting the concentration of glyphosate through the colorimetric method by utilizing ZnTCPP-coated ZIF-90 comprises the following steps: S2, preparing glyphosate with different concentrations as a standard solution, adding the standard solution into an MOFs composite material solution, adding an OPD solution into a system, performing illumination incubation, and establishing a linear relationship between the concentration of glyphosate and ultraviolet absorption intensity/fluorescence intensity; and S3, de
