摘　　要：研究聚酰胺树脂对木犀草素静态吸附热力学的特征。测定不同温度下吸附等温线热力学性能的变化,确定在实验范围内,聚酰胺树脂对木犀草素的吸附符合Langmuir吸附等温式,并利用热力学函数关系式计算了吸附焓(△H)、自由能(△G)和吸附熵值(△S),表明吸附过程是自发进行且伴随着放热的物理吸附过程。Thermodynamics of adsorption of luteolin by polyamide was studied. The equilibrium isotherms were obtained in a range of temperatures, and the equilibrium data obtained in the study have been found to fit the Langmuir adsorption isotherm. Thermodynamics parameters depict the exothermic nature of physical adsorption and the process is spontaneous and favorable. The heat of adsorption （△H）, Gibbs free energy （△G）, entropy of adsorption （△S） were calculated according to the relationship of the thermodynamic function.
