摘　　要：利用结构相似的异甘草素和甘草素在多壁碳纳米管(MWNTs)上的吸附差别研究了MWNTs的吸附选择性,通过吸附速率试验和等温吸附试验比较了MWNTs对异甘草素和甘草素吸附能力。结果显示,异甘草素和甘草素在MWNTs上的吸附行为符合Langmuir模型,接近于均匀表面上的单层吸附;MWNTs对异甘草素的吸附能力强于对甘草素的吸附。结果表明:多壁碳纳米管对结构相似的异甘草素和甘草素的吸附具有选择性。To investigate adsorptive selectivity of multi-walled carbon nanotubes （MWNTs） to structure similarly isoliquiritigenin and liquiritigenin through the adsorption experiments.Different adsorbabilities of MWNTs to isoliquiritigenin and liquiritigenin were obtained by superficial syndrome,adsorption rate and isothermal adsorption experiments.The results showed that the adsorbability of MWNTs to isoliquiritigenin was stronger than to liquiritigenin.Isothermal adsorption experiments suggested adsorption processes of isoliquiritigenin and liquiritigenin on MWNTs to be fitted Langmuir model and close to monolayer adsorption on homogeneous surface,which revealed the adsorption selectivity from the adsorption process of multi-walled carbon nanotubes to structure similarly isoliquiritigenin and liquiritigenin.
