摘要: 应用表面增强拉曼散射光谱(SERS)技术,研究0.5%HCl体系中缓蚀剂在18-8不锈钢表面的吸附.谱图是在不锈钢表面电沉积不连续Ag颗粒条件下测得的.缓蚀剂BMAT通过电极表面与缓蚀剂中的N原子,以及苯并咪唑环的共轭大π键形成化学吸附,BMAT斜卧于电极表面.其烯丙基起到空间的阻碍的作用.

Abstract: The absorbtion of some nitrogen and sulfur compounds such as BMAT on 18-8stainless steel(SS)in 0.5% HCl were investigated by surface enhanced Raman scattering(SERS)spectroscopy.The SERS spectra of BMAT adsorbed on SS were measured using a SS electredepositedwith discontin uous silvet micro-islands.The results show that the inhibitor,BMAT,is chemisorbed onthe SS surface through the N atom. Under the influence of π-electron interaction ,BMAT can beadsorbed on SS surface at an angle. The allyls in BMAT molecules play the role of steric hindrance inthe inbibition effect.

Key words: Raman spectroscopy, stainless steel, inhibition
