摘要
本文运用表面增强拉曼散射光谱（ＳＥＲＳ）技术，研究在０．５％ＨＣｌ体系中缓蚀剂在１８—８不锈钢表面的吸附模式。这些ＳＥＲＳ谱图是籍在不锈钢表面电沉积不连续Ａｇ颗粒得到的。缓蚀剂ＢＭＡＴ在电极表面的吸附是通过电极表面与缓蚀剂中的Ｎ原子形成化学吸附，以及苯并咪唑环的共轭大π键的化学吸附，缓蚀剂斜卧于电极表面。ＢＭＡＴ的烯两基起到空间阻碍的作用。
The adsorption of some nitrogen and sulfur compounds such as BMAT on 18-8 stainless steel(SS) in 0.5% HCl were investigated by surface enhanced Raman scattering(SERS)spectroscopy.The SERS spectra of BMAT adsorbed on the SS were measured using a SS electrode with discontinuous micro-islands of silver prepared by electrodeposition.The inhibitor,BMAT were chemisorbed on the SS surface through the N atom.Under the influence of π-electron interaction, BMAT could be adsorbed on SS surface at an angle.Allyl of BMAT played a role in the inhibition effect by the steric hindrances.
