The invention discloses a bis-pyrazol functional lead-imprinted FDU-12 material as well as a preparation method and application thereof. The preparation method comprises the following steps: adding TEPIC into a mixture of a DPP lead complex, alkali and tetrahydrofuran, heating for reflux, completely extracting a solvent under a vacuum state, adding toluene and a mesoporous material FDU-12 for reaction, and carrying out acid pickling to remove lead, so as to obtain the bis-pyrazol functional lead-imprinted FDU-12 material. The bis-pyrazol functional lead-imprinted FDU-12 material disclosed by the invention has high selective adsorbability to lead ions, strong disturbance resistance to co-existing ions and strong regeneration capacity. A developed detection method has the advantages of highdetection precision, good precision and high detection efficiency.
