Embodiment 1
[0044] (1) CoFe 2 o 4 Preparation: Weigh 4mmolFeCl 3 ·6H 2 O and 2 mmol CoCl 2 ·6H 2 O was added to 70mL of ethylene glycol to form a clear solution, then 30mmol of ammonium acetate was added, and stirred vigorously at room temperature for 30min, then the mixture was put into a stainless steel autoclave and sealed, and reacted at 210°C for 48h. After the reaction kettle was cooled to room temperature, it was washed and dried in vacuum at 50°C for 12 hours to obtain CoFe 2 o 4 .
[0045] (2) Preparation of poly-o-phenylenediamine (POPD): Weigh 2.16g of o-phenylenediamine (OPD) and dissolve it in 30mL of chloroform to form an organic phase solution; then dissolve 2.128g of ammonium persulfate in 30mL of distilled water , dubbed into an aqueous solution. Then the organic phase was first moved into a jar, and then the aqueous solution was drained through a glass rod and added to the jar, left at room temperature for 24 hours, washed and dried in vacuum at 50°C for 12 hours...
Embodiment 2
[0053] Carry out the same steps of the preparation process in Example 1, except that the addition of Ag-POPD in step (4) is 0.01g, 0.05g, 0.1g, 0.5g, 1g respectively, to prepare different Ag-POPD embedded magnetic The imprinted photocatalyst was investigated to investigate the effect of different Ag-POPD additions on the photocatalytic activity of the Ag-POPD embedded magnetically imprinted photocatalyst, and the photodegradation activity of the ciprofloxacin solution was investigated according to the step (6) in Example 1. The photocatalytic effect is as Figure 8 As shown, it can be seen that the Ag-POPD embedded magnetically imprinted photocatalyst prepared when the amount of Ag-POPD added is 0.1 g has the best photodegradation effect on ciprofloxacin.
Embodiment 3
[0055] Carry out the same steps according to the preparation process of Example 1, the difference is that the microwave polymerization time in step (4) is 20min, 40min, 60min, 80min, 100min respectively, to prepare different Ag-POPD embedded magnetic imprinted photocatalysts, investigate different microwave The effect of polymerization time on the photocatalytic activity of the Ag-POPD embedded magnetically imprinted photocatalyst was investigated according to the step (6) in Example 1 to investigate the photodegradation activity of the ciprofloxacin solution. The photocatalytic effect is as Figure 9 As shown, it can be seen that when the microwave polymerization time is 60min, the prepared Ag-POPD embedded magnetically imprinted photocatalyst has the best photodegradation effect on ciprofloxacin.
[0056] figure 1 It is the XRD spectrum of different samples. It can be seen from the figure: the line a is consistent with the standard spectrum of Ag, and the line b is consiste...
