Magnetic covalent organic frame material and preparation method and application thereof

The invention discloses a magnetic covalent organic frame material and a preparation method and an application thereof. The magnetic covalent organic frame material takes piperazine and cyanuric chloride as the construction units to form a covalent organic frame, and then the covalent organic frame is loaded on the organic frame material formed on the surface of magnetic ferriferrous oxide. The organic frame material better solves the problems of small particle size, poor stability and difficult separating from a water body of the current covalent organic frame materials. The method employs a solvothermal method, and akes the magnetic ferriferrous oxide nano particles as a carrier, the material is immersed into a piperazine-containing ligand solution, a cyanuric chloride ligand solution is dropped, and a hydro-thermal reaction is carried out under constant temperature condition to obtain the magnetic covalent organic frame material. The material has the characteristics of strong separating capability in water
