摘要

摘要: 多壁碳纳米管可选择性地吸附结构相似的两种黄酮类化合物甘草苷和异甘草苷，研究了异甘草苷被多壁碳纳米管吸附的吸附热力学特征。结果表明：多壁碳纳米管吸附异甘草苷的量随着异甘草苷浓度的增加而增加，随着温度升高而降低。异甘草苷的吸附过程符合Freundlich方程。其ΔH₀和ΔG₀值表明该吸附反应是自发进行的放热反应。

Abstract: Multiwalled carbon nanotubes (MWCNTs) can selectively adsorb structurallysimilar liquiritin and isoliquiritin, both of which are flavonoid compounds. The adsorption thermodynamics of isoliquiritin on MWCNTs was investigated. Results indicate that the quantity of isoliquiritin adsorbed increases with isoliquiritin concentration and decreases with temperature. Adsorption data can be well described by the Freundlich Equation. The values of ΔH₀ and ΔG₀ indicate that the adsorption is a spontaneous exothermic process.
