Abstract: The invention relates to a process for preparing a modified silica nanometer molecularly imprinted polymer capable of separating saccharin sodium, aiming at solving the existing problem of no molecularly imprinted polymer capable of separating saccharin sodium. The process comprises the following steps: 1. preparation of SiO2 nanometer particles; 2. preparation of amino modified SiO2 nanometer particles; and 3. preparation of modified silica nanometer molecularly imprinted polymer. The modified silica nanometer molecularly imprinted polymer capable of separating saccharin sodium prepared according to the process has the maximal saturated adsorption capacity of 8.5-9.5 mg/g, high adsorption efficiency and short adsorption time of 180 minutes, still has 90 percent of the original adsorption efficiency after being stored under the ambience of nitrogen and high repeated utilization rate, and can be applied to the field of separation of saccharin sodium.
