The invention relates to a preparation method of a micron-sized metal organic framework material. The method comprises the following steps that S1) dissolving divalent manganese salt and bptc in deionized water, adding NaOH to enable the concentration of manganese ions to be 0.01 mol/L to 0.6 mol/L and the concentration of NaOH to be 0.01 mol/L to 0.9 mol/L, and stirring the mixture at room temperature to obtain a solution A; S2) dissolving 4-bpdh in methanol to ensure that the concentration of the 4-bpdh in the methanol is 0.01-0.6 mol/L, and stirring the mixture at room temperature to obtaina solution B; S3) slowly adding the solution B into the solution A, continuously stirring the mixed solution to enable the two solutions to react for 10 minutes to 10 hours, performing suction filtration, and drying a reaction product to obtain the Mn(bptc)(4-bpdh). Compared with the prior art, the metal organic framework material Mn(bptc)(4-bpdh) is synthesized by adopting a one-step precipitation method. The method is
