摘要
研究了20℃时碳纳米管对苯酚和α-萘酚的吸附,测定了不同浓度下碳纳米管对它们的吸附量,并采用Langmuir方程进行拟合,根据1H质子宽线氢谱和热重分析对吸附结果进行了探讨。结果表明,碳纳米管对α-萘酚的吸附能力较对苯酚的吸附能力强,碳纳米管与α-萘酚之间存在较强的π-π共轭作用,而与苯酚之间的π-π共轭作用较弱。
The adsorption of phenol and α-naphthol from aqueous solution onto carbon nanotubes was studied at 20℃ The adsorption isotherms were measured and the results were fit with Langmuir equation. The results of ^1 H NMR, TG and adsorption were discussed, α-Naphthol was more readiliy adsorbed than phenol showing that there is a stronger π-π stacking interaction between the carbon nanotubes and α-naphthol than that between the carbon nanotubes and phenol.
