The invention relates to a preparation method of a water-stabilized triazine-based metal organic framework material, and belongs to the technical field of metal organic framework materials. The method is as follows: dissolving bismuth metal salt and triazine-based organic acid in an organic solvent, and preparing by solvothermal method to obtain CAU-7-TATB, namely Bi and 2,4,6-tris(4-carboxybenzene base)-1,3,5-triazine metal organic framework material. The triazine-based CAU-7-TATB synthesized by the solvothermal method in the present invention has good water stability, and even when placed in an aqueous solution for seven days, structure collapse and metal leakage will not occur; it is very suitable for the adsorption of heavy metal ions; Moreover, this CAU-7-TATB does not require post-modification, and uses the N atom on the triazine group to directly play an adsorption role, and has a good adsorption effect on various heavy metal ions, especially the adsorption of lead ions. and excellent selectivity. |
