| 摘 要： | 本文用电化学现场表面增强拉曼散射光谱（ＳＥＲＳ）技术研究了ＭＴＵ在ＨＣｌＯ４、Ｈ２ＳＯ４和ＨＮＯ３介质中分别与一种或两种无机阴离子的共吸附行为，发现ＣｌＯ－４、ＳＯ２－４和ＮＯ－３等弱吸附无机阴离子均能被ＭＴＵ诱导物理吸附在其质子化了的氨基（ＮＨ＋３）上，这三种无机阴离子被ＭＴＵ诱导物理吸附的强弱顺序是：在电极电位位于－０．２Ｖ～－０．７Ｖ区间时，ＳＯ２－４＞ＣｌＯ－４＞ＮＯ－３，在电位位于－０．８Ｖ～－１．２Ｖ区间时，ＣｌＯ－４＞ＳＯ２－４＞ＮＯ－３。

| Abstract: | Using surface enhanced Raman spectroscopy (SERS), we have studied the coadsorption of 1 methyl 2 thiourea (MTU) with one or two kinds of inorganic anions in perchloric acid, sulphuric acid, nitric acid medium respectively at silver electrodes. The results indicate that inorganic anions with weak coadsorbability such as ClO - 4,SO 2- 4 and NO - 3 can be physically induced to absorb through the protonated amino group of MTU. It was found that the coadsorbability of these anions with MTU is in the order of SO 2- 4>ClO - 4>NO - 3 in the potential region from -0 2V to -0 7V and ClO - 4>SO 2- 4>NO - 3 in the potential region from -0 8V to -1 2V. |
