Abstract

The invention discloses a metal-organic framework material as well as a preparation method and application thereof. The chemical formula of the metal-organic framework material is [Cu (btr) 2 (hpztr) 2 (pztr<-1>) 2 (NO3<->) 3] n, wherein Hpztr is 4-(3, 5-dimethylpyrazole-4-yl)-1, 2, 4-triazole, and btr is 4, 4'-bis-1, 2, 4-triazole. The preparation method of the material comprises the following steps of: (1) synthesizing Hpztr; (2) synthesizing btr; (3) dissolving copper salt, Hpztr and btr by using a mixed solvent to obtain a mixed solution; and (4) placing the mixed solution in a constant-temperature drying box at 90-100 DEG C for reaction, cooling to room temperature, filtering, washing and drying to obtain the metal-organic framework material. The material can be applied to removal of ions in water. The material has relatively high thermal stability and chemical stability. Anions in water can be effectively adsorbed and enriched at normal temperature and normal pressure, and particularly, the adsorption rate is high and the adsorption capacity is large. The material can be used as an efficient water purifying adsorbent for removing water from water.

Description

technical field

[0001] The present invention relates to a material and its preparation method and application, more specifically, to a metal-organic framework material and its preparation method and application. Background technique

[0002] As one of the most precious natural resources on the earth, water is of irreplaceable importance to the survival and development of human beings, animals and plants. However, with the expansion of the scope of human activities and the rapid development of modern industry, water pollution has become increasingly serious and has become a serious problem faced by the whole world. Disposal of industrial waste, discharge of chemical wastewater, leakage of nuclear waste and excessive use of pesticides have introduced various harmful substances into water bodies. Common heavy metal ions in wastewater mainly include arsenic, copper, chromium, lead, mercury, nickel and zinc ions. Excessive levels of these ions will pose a huge threat to the sur...
