Preparation method and application of covalent organic framework photocatalyst with gold nanocluster and magnetism

The invention discloses a preparation method and application of a covalent organic framework photocatalyst with gold nanoclusters and magnetism, and belongs to the technical field of analysis and photocatalytic degradation removal of chlorobenzene pollutants in water. The problems that chlorobenzene compounds in a water body are difficult to detect and degrade by an existing catalyst, the visible light utilization rate is low, the catalytic efficiency is low, and solid and liquid are difficult to separate are solved. The magnetic covalent organic framework photocatalyst material based on gold nano-cluster embedding, which can be used for analyzing, degrading and removing chlorobenzene pollutants in water, is prepared, and a magnetic solid-phase extraction method using the material is combined with a gas chromatography-tandem mass spectrometry technology, so that the content of chlorobenzene compounds in water is qualitatively and quantitatively analyzed; in addition, under the action of visible light, rapid d
