Problems solved by technology

To apply FMOFs materials to the detection of antibiotic pollutants in water, the first thing to solve is the water stability of such materials
In general, in aqueous solution, the structure of FMOFs materials is easily attacked by water molecules, resulting in ligand substitution, structural collapse, and material decomposition.

Abstract

The invention belongs to the field of metal organic framework materials, and relates to an FMOF material with high water stability, preparation of the FMOF material and application of the FMOF material in sensing detection of fleroxacin in water. The preparation method comprises the following steps: taking cadmium salt and N, N '-bis (4-carboxyl-3, 5-dimethylphenyl)-1, 4-naphthalimide (H2L) ligand as raw materials, dissolving the raw materials in an organic solvent according to a certain proportion, and synthesizing the FMOF material by adopting a solvothermal method. The preparation process is simple, and the water stability of the material is high; the synthesized FMOF material has the advantages of rapidness, high sensitivity, high selectivity and the like in the aspect of detecting fleroxacin in water.

Description

Technical field [0001] The present invention belongs to the field of metal organic frame materials, and more particularly to the preparation of FMOF materials having high water stability and its fluorescence sensing detection of fluoroxs in water. Background technique [0002] The information disclosed in the background is only intended to increase the understanding of the overall background of the present invention, and is not necessarily considered to recognize or imply that the information is intended to be a prior art known to those of ordinary skill in the art. [0003] Fluoxsham is the third-generation quinolone antibiotics, with strong tissue penetration, high bioavailability, elimination of half-life, etc., has a strong killing effect on multiple Gram-positive bacteria and Gram-negative bacteria. Most of its drug prototypes are excreted into ambient water body. In recent years, as Fluoxshaxing is excessive use or even abused, it has brought significant pollution to some e...
