摘　　要： 运用频率响应方法（Frequency Response）研究了正辛烷在Cu（Ⅱ）Y上的吸附行为,在温度为373 K和302 K,压力为（0.133~0.399）kPa时绘制频率响应谱图,并根据频率响应谱图计算每个吸附过程的动力学参数。研究结果表明,正辛烷在Cu（Ⅱ）Y上的吸附以吸附为速率控制步骤,且吸附能力较弱,正辛烷在Cu（Ⅱ）Y上的吸附在一定的温度、压力条件下,高频吸附是由物理吸附为主,低频吸附是由一些相互作用为主。 Frequency response（FR） technique was used in the study on adsorption behaviors of n-octane on Cu（Ⅱ）Y zeolite.FR spectra of n-octane on Cu（Ⅱ）Y were recorded at（0.133～0.399）kPa and 302～373 K,and kinetic parameters for each adsorption process were derived from the FR spectra.The results indicated that adsorption was the controlling step.And adsorption ability was weak.Adsorption of n-octane on Cu（Ⅱ）Y was high-frequency absorption is mainly due to physical adsorption,low-frequency absorption is mainly due to some interaction.
