【摘要】：随着我国城市化和工业化进程的加快,水资源短缺和水污染问题日益突出.碳纳米管复合膜由于其结合了膜材料和碳纳米管的优良性能,在水处理应用中具有良好的应用前景,已成为膜分离领域的研究热点之一.本文在简要介绍碳纳米管的制备和生长机理的基础上,综述了碳纳米管复合膜的制备及其在海水淡化、油水分离、重金属离子和新兴污染物去除方面的应用研究进展.通过对碳纳米管复合膜及水处理研究所面临问题的简要分析,提出今后的研究重点应主要集中在降低通过复合膜成本、膜性能改善和应用拓展方面,使其尽快在环境水处理领域推广应用.
[Abstract]:With the acceleration of urbanization and industrialization in China, water shortage and water pollution are becoming more and more serious. Carbon nanotube composite membrane has a good application prospect in water treatment because it combines the excellent properties of membrane materials and carbon nanotubes. In this paper, the preparation and growth mechanism of carbon nanotubes (CNTs) are briefly introduced, and the preparation of CNTs composite membranes and their applications in desalination of seawater and separation of oil and water are reviewed. Based on the brief analysis of the problems faced by carbon nanotube composite membrane and water treatment research, it is pointed out that the emphasis of future research should be mainly on reducing the cost of the composite membrane. In the aspect of performance improvement and application expansion, the membrane can be popularized and applied in the field of environmental water treatment as soon as possible.
