The invention relates to the technical field of mercury ion imprinting adsorption, in particular to a preparation method of a mercury ion surface imprinting adsorption material. The method comprises the following steps: preparing silicon dioxide gel from organosilane, and calcining to obtain silicon dioxide microspheres; carrying out activating treatment on the silicon dioxide microspheres to obtain activated silica gel; carrying out silanization treatment on the activated silica gel to obtain silanized silica gel; the preparation method comprises the following steps: dissolving mercury salt and a monomer in an organic solvent, adding N, N-dimethylformamide for reaction, then adding silanized silica gel for reaction, and then adding a coupling agent and an initiator for reaction to obtain the mercury ion surface imprinting adsorption material. The mercury ion surface imprinting adsorption material prepared by the method is large in adsorption capacity (the adsorption capacity reaches 52176 mu g/g), good in se
