Beschreibung
Zusammenfassung:	The invention discloses a modified UiO-66-NH2 material as well as a preparation method and application thereof, and the modified UiO-66-NH2 material is obtained by carrying out Mannich reaction on UiO-66-NH2, 4-amino-3-hydrazino-5-sulfydryl-1, 2, 4-triazole and formaldehyde under the condition of taking hydrochloric acid as a catalyst. The UiO-66-NH2 is subjected to one-step modification by adopting a post-synthesis modification strategy, the adsorption performance and selectivity of the UiO-66-NH2 to Hg (II) are improved, the UiO-66-NH2 material shows rapid Hg (II) removal capacity, adsorption equilibrium is achieved in 90 min, the adsorption capacity is 327.88 mg/g under the conditions of 298K and pH value of 5, and the modified UiO-66-NH2 material shows good selectivity and cycling stability, can be used as a potential adsorbent material for treating wastewater containing heavy metal ions. 本发明公开了一种改性UiO-66-NH2材料及其制备方法和应用，所述改性UiO-66-NH2材料由UiO-66-NH2、4-氨基-3-肼基-5-巯基-1,2,4-三氮唑和甲醛在盐酸作催化剂的条件下发生曼尼希反应获得。本发明采用后合成修饰
