| 摘 要： | 本文采用浓硝酸氧化法来改性多壁碳纳米管,用Raman光谱、SEM和分光光度计对改性前后的多壁碳纳米管对4-硝基苯酚溶液的吸附能力进行了比较研究。Raman光谱和SEM分析表明浓硝酸处理使碳纳米管端口打开,管变短,并且在表面引入了羟基、羧基等酸性官能团。采用分光光度计测定溶液浓度,计算出浓硝酸处理前后多壁碳纳米管对不同浓度4-硝基苯酚的吸附效率,实验结果表明经浓硝酸处理后的多壁碳纳米管的吸附效率有较大的提高。

| Abstract: | Multi-wall carbon nanotubes (MWNTs) were treated by oxidation method with concentrated nitric acid, and the adsorption of p-nitrophenol on MWNTs before and after concentrated nitric acid treatment has been compared by Raman, SEM and spectrophotometer. It was found from the results of Raman and SEM that the MWNTs were cut and opened, in addition, the hydroxyl and carboxyl groups were introduced after treatment by nitric acid . The concentration of p-nitrophenol was determined by spectrophotometer, and their adsorption capacities at different concentration were worked out. The result indicates that the adsorption capacity of MWNTs after concentrated nitric acid treatment is obviously enhanced. |
