摘要
碳纳米管表面经强酸氧化处理,管体发生解体,分散,形成碳纳米管胶体,用于去除水中低浓度持久性有机污染物异狄氏剂。扫描电镜观测表明,氧化后的碳纳米管团簇被分散开,碳纳米管被打断;红外光谱测试曲线表明,硝酸氧化后的碳纳米管表面引入了大量含氧官能团。氧化前后的碳纳米管对异狄氏剂的吸附实验研究表明,氧化后碳纳米管的吸附性能优于原始碳纳米管吸附性能,且等温吸附曲线均呈线性。
Carbon nanotubes（CNTs） was oxidated by strong acid,tube dissoluted,dispersed and formed carbon nanotubes sol and used for removal of low concentration endrin,a kind of persistent organic pollutants（POPs）.Scanning electron microscopy observation showed that after oxidation,the CNTs clusters were dispersed and the tubes were broken up.Infrared spectroscopy test showed that after oxidation,carbon nanotube surface introduced a number of oxygen-containing functional groups.The adsorption of endrin experimental results showed that after oxidation CNTs had better adsorption properties for removal of endrin.
