Organic contaminants have become one of the most serious environmental problems, and the removal of organic contaminants (e.g., dyes, pesticides, and pharmaceuticals/drugs) and common industrial organic wastes (e.g., phenols and aromatic amines) from aqueous solutions is of special concern because they are recalcitrant and persistent in the environment. In recent years, carbon nanotubes (CNTs) have been gradually applied to the removal of organic contaminants from wastewater through adsorption processes. This paper reviews recent progress (145 studies published from 2010 to 2013) in the application of CNTs and their composites for the removal of toxic organic pollutants from contaminated water. The paper discusses removal efficiencies and adsorption mechanisms as well as thermodynamics and reaction kinetics. CNTs are predicted to have considerable prospects for wider application to wastewater treatment in the future.
有机污染物已成为最严重的环境问题之一，因此，去除水溶液中的有机污染物（例如染料、农药和药物/药品）和常见工业有机废物（例如酚类和芳香胺）受到特别关注，因为它们在环境中具有抗降解性和持久性。近年来，碳纳米管（CNTs）已逐渐通过吸附过程应用于从废水中去除有机污染物。本文综述了近年来（2010 年至 2013 年发表的 145 项研究）通过 CNTs 及其复合材料从受污染水中去除有毒有机污染物的应用进展。本文讨论了去除效率和吸附机制以及热力学和反应动力学。预计 CNTs 在未来将有更广阔的应用前景，可用于更广泛的废水处理。
