The invention discloses an organic framework material with fluorescence recognition of p-nitrobenzene, a preparation method and application, which are characterized in that a zirconium-based metal-organic framework material with active carboxylic acid sites is formed by using zirconium tetrachloride and an organic acid, The preparation includes: replacing a ligand and synthesizing a mixture of zirconium tetrachloride and 1,4-phthalic acid, 1,3-phthalic acid and N,N-dimethylformamide at 110-130° C., the reaction The product is modified with europium nitrate, and the product is a europium-modified zirconium-based metal-organic framework material; the organic framework material can be used for fluorescent identification of nitrobenzene in natural water. Compared with the prior art, the invention has the advantages of fluorescent identification of small molecular organic compounds, fast operation, high sensitivity, fast response speed and strong anti-interference ability, and is a fluorescent identification material with great development potential, which has potential in the field of materials science. application value. |
