A zirconium-based metal-organic framework material UiO-66(Zr) and a rapid room-temperature preparation method and application thereof are provided. The preparation method includes: (1) mixing a zirconium source and an organic ligand uniformly, then placing in methanol and stirring at room temperature, centrifuging and then discarding a supernatant to obtain a transparent gel-like intermediate product; and (2) heating and drying the intermediate product to obtain UiO-66(Zr). Compared with the prior art, the present invention excludes the use of N,N-dimethylformamide and other toxic organic solvents that are necessary in the traditional solvothermal method, and only needs to stir in methanol at room temperature and dry to obtain UiO-66(Zr). The method has mild conditions and a high yield. Moreover, the product purity is extremely high, and the product activation step can be omitted. The product has good adsorption to fluoride ion in water, and can be applied to the adsorption treatment of fluorine-containing wastewater.
