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。
碳納米管錶麵經彊痠氧化處理,管體髮生解體,分散,形成碳納米管膠體,用于去除水中低濃度持久性有機汙染物異狄氏劑。掃描電鏡觀測錶明,氧化後的碳納米管糰簇被分散開,碳納米管被打斷;紅外光譜測試麯線錶明,硝痠氧化後的碳納米管錶麵引入瞭大量含氧官能糰。氧化前後的碳納米管對異狄氏劑的吸附實驗研究錶明,氧化後碳納米管的吸附性能優于原始碳納米管吸附性能,且等溫吸附麯線均呈線性。

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.
