用表面增强拉曼光谱技术(SERS)对在3%NaCl溶液中苯并三氮唑(BTA)及其衍生物4-羧基苯并三氮唑(4CBTA)对铜的缓蚀作用机理进行了研究。发现4CBTA对铜的缓蚀作用机理与BTA相似，在较正电位下两者都是通过三唑环与铜形成配合物覆盖在铜表面；随着电位负移，铜电极表面吸附的分子形式的BTA或4CBTA数量增多； 4CBTA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。两者复配使用时以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 deriva tive 4CBTA on Cu electrode in 3% NaCl solution was studied by SERS technique. The inhibition mechanism for these inhi bitors was found to be nearly the same, which form a protective film through th e triazole ring. As the potential turns negative, the molecules of BTA or 4CBTA gradually adsorbs on the copper surface. The substitute group(—COOH) of 4CBTA a cts as a steric hindrance. A combination of BTA and 4CBTA doesn't show any syne rgistic effect and the adsorption substance on the copper surface is mainly BTA .
