| 摘 要： | 使用压电传感器原位研究己二硫醇在金表面上的吸附/解吸附液相动力学,从起始阶段到达到吸附平衡,通过线性拟合,表明吸附过程符合Langmuir吸附模型;确定己二硫醇在不同溶剂中,在Au表面吸附/解吸附的速率常数、表观平衡常数、自由能,以及通过在不同温度下的实验结果推导出反应的表观活化能,为压电传感器电极表面自组装提供基本的理论参数。

| Abstract: | The adsorption/descorption solution phase kinetic of the hexanedithiol on the golden surface has been studied in-situ by using the piezoelectric sensor.The linear fitting showed that the adsorption process satisfied the Langmuir adsorption model from the starting adsorption to reaching the adsorption balance.The adsorption/descorption rate constant on Au surface,the equilibrium constant,the free energy of adsorption on golden surface of the hexanedithiol in various solutions have been determined.The basic theoretic parameters for the self-assembly of the electrode surface in the piezoelectric secsor have been provided. |
