随着经济的快速发展,石油、天然气等行业排放大量含油废水,给生态环境造成巨大影响。因此,开发一种处理含油废水的新型材料及处理方法备受关注。金属有机框架(MOF)是一种新型微孔、结构可调的多功能材料,多变性和可修饰性的特点赋予其超疏水/超亲水性能,在油水分离中应用广泛。简述利用溶剂热法、超声波法、微波法、机械合成法和搅拌法制备MOF,及MOF对海绵、不锈网、水凝胶和过滤膜基材的修饰,以及在油水分离中的应用,并对今后MOF在水处理方面的发展进行展望。
With the rapid development of economy,oil,natural gas and other industries discharge a large amount of oily wastewater,which has a great impact on the ecological environment.The development of a new material and treatment method for oily wastewater has attracted much attention.Metal organic framework (MOF) is a new type of microporous multifunctional material with adjustable structure.Due to its variability and modifiability,the material has superhydrophobic/superhydrophilic properties and has been widely used in oil-water separation.This paper briefly described the preparation of MOF by using solvothermal method,ultrasonic wave method,microwave method,mechanical synthesis method and stirring method.It further introduced the modification of MOF to sponge,stainless steel mesh,hydrogel,filtration membrane substrate and its application in oil and water separation.It also forecasted the development of MOF in water treatment in the future.
