The preparation method comprises the following steps: carrying outchemical reaction on N, N-dimethyl p-phenylenediamine, aluminum sulfate hydrate, sodium thiosulfate, zinc chloride and potassium dichromate to obtain an intermediate 1; secondly, carrying out chemicalreaction on N-methylaniline, dimethyl pyridine, ethyl 5-bromovalerate and sodium hydroxide to obtain an intermediate 2, and carrying out chemical reaction on the intermediate 1 and the intermediate 2under the action of a catalyst silver carbonate to obtain the methylene blue hapten; and finally, after the methylene blue hapten reacts with dicyclohexylcarbodiimide (DCC) and N-hydroxysuccinimide (NHS), bovine serum albumin (BSA) is added for a reaction, and the methylene blue immunogen is prepared. According to the methylene blue immunogen prepared by the method, the coupling ratio is about 28: 1, the mouse can be stimulated to generate an antibody, the antibody titer is about 64000, the methylene blue concentration is 39.0 ng / mL when the inhibition rate is 50% and the competitive inhibition effect on methylene blue is excellent.
