摘　　要：水作为人类生活必不可少的资源,缓解人类科技发展中对于水的重金属污染问题,引起了广大关注。金属有机骨架(Metal-Organic Frameworks,MOFs)材料有很好的吸附性,可以将水中的污染物吸附分离。沸石咪唑酯骨架材料(Zeolitic Imidazolate Frameworks,ZIFs)是MOFs家族中的一个分支,这类材料有着更大的比表面积。而ZIF-8是最具代表性的一种材料,它有很好的疏水性,可以更好地在水中吸附离子。而且这种材料制备方便,成本低廉,进而成为了人们的研究热点。采用水热合成法以无水甲醇为溶剂,在高压反应釜中在60℃恒温下反应1h获得ZIF-8纳米颗粒。并利用X射线衍射仪(XRD)进行测试,分析测试结果并展望对于未来负载性能研究及其可行性。As water is an indispensable resource for human life,great attention has been paid to alleviating the problem of heavy metal pollution of water as a result of the development of human science and technology.Metal-organic Frameworks(MOFs)materials can adsorb and separate pollutants in water.Zeolitic Imidazolate frameworks(ZIFs)are a branch of the MOFs family that have a larger specific surface area,of which ZIF-8 is the most representative for its good hydrophobicity can better adsorb ions in water.Moreover,this material is convenient to prepare at a low cost,which has become a research hotspot.In this paper,ZIF-8 nanoparticles were obtained by hydrothermal synthesis using anhydrous methanol as solvent,and reacting in a high-pressure reactor at a constant temperature of 60°C for 1h.X-ray diffractometer(XRD)was used to analyze the test results together with an outlook to the future of its load performance studies and its feasibility.
