The invention discloses a method of one-pot preparation of a UIO-66-NH2 / functional monomer composite material, and an application of the composite material for adsorption of antibiotics. The method includes: simultaneously dissolving the functional monomer, a zirconium source, and an organic ligand in N,N-dimethylformamide under supersonic, adding a crosslinker ethylene glycol dimethacrylate and an initiator azodiisobutyronitrile; moving the materials into a stainless steel reaction kettle with a Teflon liner, and performing a reaction at 100-150 DEG C for coordination and bonding; cooling thereaction product, and washing, centrifuging and drying the product to obtain the target product, UIO-66-NH2 / functional monomer composite material. The invention also discloses an application of the composite material, as an adsorbent, for adsorbing macrolide antibiotics. Through the one-pot process, the UIO-66-NH2 / functional monomer composite material has excellent physical and chemical stability. The method is simple in process, is environment-friendly. The material is high in removal efficiency and large in adsorption capacity on the macrolide antibiotics in environment.
