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.
