The invention relates to the technical field of organic functional materials, in particular to an adsorbent material and a preparation method and application thereof, a material framework of the prepared adsorbent material is rich in N/O atom effective adsorption sites, the adsorption capacity on Pb < 2 + > is high and is 418.41 mg/g, the material stability is good, and the adsorption efficiency is high. The adsorption mechanism is mainly related to structurally rich N atoms and O atoms and a pore structure with a large specific surface area, important significance is achieved for lead metal recovery, and the prepared adsorption material is simple and easy in raw material obtaining, simple and effective in synthesis method, lower in cost, higher in adsorption capacity, good in selectivity, capable of being recycled and suitable for industrial production. The method has application prospects in the aspects of removing heavy metal Pb < 2 + > and recovering lead metal. 本发明涉及有机功能性材料技术领域，具体涉及一种吸附剂材料及其制备方法和应用，制备的吸附
