Cu电极上咪唑与苯并三唑共吸附的SERS研究

STUDY ON THE COADSORPTION OF IMIDAZOLE AND BENZOTRIAZOLE ON THE COPPER ELECTRODE WITH SERS

用表面增强拉曼散射（ＳＥＲＳ）技术研究了缓蚀剂咪唑（ＩＭ）与苯并三唑（ＢＴＡＨ）在铜电极上的共吸附行为．实验表明，ＩＭ与ＢＴＡＨ能共吸附于Ｃｕ电极表面，ＩＭ的存在有利于ＢＴＡＨ的吸附，二者有良好的协同效应．

A comparison of the SERS of Imidazole(IM), Benzotriazole(BTAH) and their mixture has been made for the first time. The coadsorption of IM and BTAH on the copper electrode was discussed based on SERS spectra. The experimental results indicated that SERS intensity of BTAH increases in the presence of IM.There is a strong synergistic action between the two corrosion inhibitors.SERS can be a useful surface analytical technique for the detection of interaction between inhibitor and metal surface.
