金属-有机骨架(MOF)由于其具有诱人的特性,近年来在消除有毒污染物方面受到了广泛关注。UiO-66具有热稳定性好,遇热不易分解;优异的化学稳定性,在空气、水、氯仿及多种溶剂条件下都不易分解或变性;对高外压具有优异的耐受性能等特性。主要原因是锆团簇与有机配体之间的强Zr—O键和高配位数。这些优良的特性使其在废水处理中有许多潜在的应用。主要简述了将UiO-66作为优良的水稳定性MOF用于高效去除(吸附分离和降解)有机染料,并对其今后在废水处理方面的发展进行展望。

Metal organic frameworks(MOFs)have received widespread attention in recent years in eliminating toxic pollutants due to their attractive properties.UiO-66 has good thermal stability and is not easily decomposed when exposed to heat.UiO-66 also exhibits excellent chemical stability,resistance to decomposition or denaturation under conditions of air,water,chloroform,and various solvents,and outstanding resistance to high external pressure and other characteristics.The main reason is the strong Zr—O bond and high coordination number between zirconium clusters and organic ligands.These exceptional characteristics make it have many potential applications in wastewater treatment.This article mainly outlined the use of UiO-66 as an excellent water stable MOF for the efficient removal(adsorption separation and degradation)of organic dyes,and prospected its future development in wastewater treatment.
