采用表面增强拉曼光谱技术(SERS)研究了w=0.03 NaCl溶液中BTA(苯并三氮唑)及其衍生物5CBTA(5-羧基苯并三氮唑)对铜的缓蚀作用机理，发现5CBTA对铜的作用与BTA的作用机理相似，在较大正电位下两者都是通过三氮唑环与铜形成配合物覆盖在铜表面，随着电位负移在铜电极表面吸附的聚合物膜逐渐转化为分子形式吸附，5CBTA中的-COOH基团只是起到空间位阻的作用，没有参与电极表面的吸附。两者复配使用以BTA吸附为主，其缓蚀机理没有发生改变，也没有产生协同效应。

The corrosion inhibition of BTA and its derivative 5CBTA on Cu in 3% NaCl solution were studied by SERS technique. As from a protective film through the triazole ring, the inhibition mechanism for these inhibitors are found to be nearly the same. When the potential turn to negative, the molecules of BTA or 5CBTA are gradually adsorbed on the copper surface. The substitute group (-COOH) of 5CBTA acts as a steric hindrance. A combination of BTA and 5CBTA doesn't show any synergistic effect and the adsorption substance on the copper surface is mainly BTA.
