The invention relates to a preparation method of molecularly imprinted hydrogel based on metal autocatalysis, and belongs to the technical field of molecularly imprinted polymers. Comprising the following steps: preparing a metal catalyst and molecularly imprinted hydrogel, uniformly mixing template molecules and functional monomers in deionized water, standing, adding a metal catalyst solution, uniformly mixing with methylene bisacrylamide, adding ammonium persulfate, uniformly mixing, standing at room temperature for 2 hours, and eluting the template molecules. The method has the beneficial effects that on the basis of a metal autocatalysis principle, a metal catalyst is used for inducing APS to generate hydroxyl free radicals to polymerize molecularly imprinted hydrogel, and the metal catalyst used in the method can be obtained only by stirring silver acetate, tannic acid and deionized water at room temperature in the preparation process; in the hydrogel polymerization process, the use of heating, ultravio
