Polyacid-based metal organic framework material capable of being used for adsorbing antibiotics and preparation method and application of polyacid-based metal organic framework material

The invention belongs to the technical field of materials, and particularly relates to a polyacid-based metal organic framework material for adsorbing antibiotics as well as a preparation method and application of the polyacid-based metal organic framework material. The polyacid-based metal organic framework material capable of being used for adsorbing antibiotics is prepared according to a methodcomprising the following steps: (1) preparing a mixed solution containing metal ions and organic ligands, and stirring for 0.1-12 h; and (2) adding Keggin type polyacid into the mixed solution obtained in the step (1), and carrying out hydrothermal reaction to obtain the polyacid-based metal organic framework material, (3) washing and drying the polyacid-based metal organic framework material obtained in the step (2); and (4) activating the polyacid-based metal organic framework material to remove water molecules in the metal organic framework material to obtain the polyacid-based metal organic framework material for
