The invention relates to a bisphenol A dummy template molecular imprinting stirring rod of and a preparation method thereof, which is characterized in that an alkylated glass rod is used as a carrier, composite macromolecule coating is coated so as to obtain the stirring rod, and the macromolecule coating is bisphenol A dummy template molecular imprinted polymer. The composite process of the bisphenol A dummy template molecular imprinted polymer on the glass rod is as follows: the surface of the glass rod, on which silanol is exposed, is treated by silanization, then reacts with tetrabromobisphenol A, tetra-vinylpyridine, ethylene glycol dimethacrylate and azobisisobutyronitrile, and then the dummy template molecule tetrabromobisphenol A is eluted so as to obtain the bisphenol A dummy template imprinted polymer. The bisphenol A dummy template molecular imprinting stirring rod obtained by the invention is high in specific selectivity of bisphenol A, is good in interference resisting capacity, is high in sensitivity, is free from template leakage problem, and is high in the measurement accuracy of trace bisphenol A in water-bearing medium.
