Embodiment 1

[0045] This embodiment provides a method for preparing a functionalized magnetic bipyridyl coordination polymer, the method comprising the following steps:

[0046] Step 1, Cu-BPy / Fe 3 o 4 Preparation of:

[0047] 4,4'-bipyridine (4,4'-Bipyridine) and anhydrous copper sulfate (CuSO 4 ) were mixed in a molar ratio of 1:1, and ethanol (V):water (V)=1:1 solution was added, that is, 50 mL of ethanol solution was added to every 1 mol of anhydrous copper sulfate. Stir and mix evenly, and ultrasonically disperse Fe in aqueous solution for 10 min 3 o 4 Magnetic nanoparticles (addition amount is 1 / 10 of the mass of 4,4'-bipyridine) were added to the above mixed solution, stirred at room temperature for 1 hour, the mixture was suction-filtered, washed with absolute ethanol three times, and the filter cake was dried at 120°C for 12 hours to obtain Powdered solid, that is, magnetic bipyridyl coordination polymer Cu-BPy / Fe 3 o 4 .

[0048] Step 2, Cu-BPy / Fe 3 o 4 Preparation of / ...

Embodiment 2

[0052] This example provides a preparation method of a functionalized magnetic bipyridine coordination polymer. The other steps of the method are the same as in Example 1, the only difference being that the magnetic bipyridine coordination polymer Cu-BPy / Fe 3 o 4 The mass ratio to SDS is 1:2.

[0053] The Fourier transform infrared spectrogram of the present embodiment is basically the same as that of Embodiment 1.

Embodiment 3

Description

technical field [0001] The invention belongs to the field of antibiotic removal, relates to quinolone antibiotics, in particular to a preparation method and application of a functionalized magnetic bipyridyl coordination polymer. Background technique [0002] Studies in recent years have shown that antibiotics, especially tetracyclines, sulfonamides, and quinolones, are widely used in the treatment of human and animal diseases, and are also added to animal feed at subtherapeutic doses for a long time to prevent diseases and promote growth. In recent years, typical pharmaceuticals, second only to sterols, have become new pollutants that have attracted much attention. After being ingested by humans and animals, only a small amount of antibiotics is metabolized or absorbed, and more than 75% of antibiotics are excreted into the environment with feces and urine. Small doses of antibiotics can cause certain harm to the ecological environment and human health. The specific manifes...
