摘　　要：测定30和50℃下噻吩、苯并噻吩单组分及双组分在Cu(I)-13X上的吸附等温线.采用Langmuir模型对单组分平衡数据进行关联;采用修正的Langmuir模型对噻吩-苯并噻吩二组分吸附平衡进行关联.结果表明:苯并噻吩在与噻吩的竞争吸附中占据优势,30℃时噻吩和苯并噻吩吸附平衡量的计算值与实验值的误差分别为3.6%和2.4%;而50℃时噻吩和苯并噻吩吸附平衡量的计算值与实验值误差分别为3.5%和2.2%;Langmuir模型在不同温度下对二元组分具有一定适用性.The adsorption equilibrium data of monoeomponent, bi-eomponent of thiophene and benzothiophene on Cu（I）-13X were measured by the static method at 30 ℃ and 50 ℃. Benzothiophene played a predominant role in competitive adsorption with thiophene. Adsorption equilibrium data of individual thiophene and benzothiophene were both properly fitted with Langmuir model, and the modified Langmuir adsorption model was suitable to describe characteristics of thiophene-benzothiophene adsorption system. The errors of calculating and experimental data were 3.6% and 2.4% at 30 ℃ , and the errors of calculating and experimental data were 3.6% and 2.4% at 50 ℃. The result indicated that the Langmuir model was suitable for the binary adsorption system at different temperatures.
