Embodiment 1

[0050] Synthesis of luminescent metal-organic framework materials: Weigh 55.2mg of indium(III) nitrate hexahydrate and 16.6mg of 1,4-naphthyl bis(benzoic acid) and dissolve in 5.0mL N,N-dimethylformamide solvent, ultrasonically dissolve Finally, the solution was placed in a stainless steel reactor lined with polytetrafluoroethylene, reacted at a constant temperature of 120°C for 72 hours, and cooled to room temperature at a constant rate of 5°C / h to obtain transparent block crystals. The product was filtered, washed with N,N-dimethylformamide, dried at room temperature, and collected. The yield was about 82%.

Embodiment 2

[0052] Synthesis of luminescent metal-organic framework materials: Weigh 39.6mg of indium(III) chloride tetrahydrate and 16.6mg of 1,4-naphthyl bis(benzoic acid) and dissolve in 5.0mL N,N-dimethylformamide solvent, After ultrasonic dissolution, the solution was placed in a stainless steel reaction kettle lined with polytetrafluoroethylene, reacted at a constant temperature of 120°C for 72h, and cooled to room temperature at a constant rate of 5°C / h to obtain transparent block crystals. The product was filtered, washed with N,N-dimethylformamide, dried at room temperature, and collected. The yield was about 70%.

Embodiment 3

[0054] Synthesis of luminescent metal-organic framework materials: Weigh 36.8mg of indium(III) nitrate hexahydrate and 16.6mg of 1,4-naphthyl bis(benzoic acid) and dissolve in 5.0mL N,N-dimethylformamide solvent, ultrasonically dissolve Finally, the solution was placed in a stainless steel reactor lined with polytetrafluoroethylene, reacted at a constant temperature of 120°C for 72 hours, and cooled to room temperature at a constant rate of 5°C / h to obtain transparent block crystals. The product was filtered, washed with N,N-dimethylformamide, dried at room temperature, and collected. The yield was about 63%.

Abstract

The invention provides a luminescent metal organic framework material for detecting antibiotic contaminants in water. The luminescent metal organic framework material is prepared from an indium salt and 1,4-naphthyl bis(benzoic acid) by adopting a solvothermal method. The luminescent metal organic framework material has a chemical sensing function and can be used for detecting nidazole-class antibiotic contaminants in water. The luminescent metal organic framework material is simple in preparation technology, high in material purity, and good in stability; and the synthesized luminescent metalorganic framework material has the advantages of rapidness, simplicity, convenience, high sensitivity and the like in the detection of nidazole-class antibiotics, and has broad application values.

Description

technical field [0001] The invention belongs to the field of metal organic framework materials, in particular to a luminescent metal organic framework material for detecting antibiotic pollutants in water. Background technique [0002] Antibiotics are commonly used drugs for the treatment of bacterial infections. Since the British scholar Alexander Fleming first discovered penicillin in 1929 and applied it clinically in 1941, it has been widely used to treat bacterial infections in humans and animals. Although antibiotics play a huge role in the treatment of bacterial infections, studies have shown that there are varying degrees of antibiotic abuse in all countries in the world, especially in my country. The abuse of antibiotics not only leads to serious drug resistance in humans and animals, but also a large amount of antibiotic residues are discharged into the environment through metabolism, causing serious water pollution. Therefore, the detection of antibiotic pollutant...
