AMT在青铜电极表面上吸附的SERS研究
摘要:
对AMT在青铜上的吸附行为进行激光拉曼电化学研究，通过改变青铜电极的电极电位对在有无Cl－存在条件下各主要拉曼振动峰进行观察.结果表明, AMT垂直吸附在青铜表面，有Cl－存在下， Cl－与AMT分子共吸附在青铜表面上.外加阳极极化电流、加入Cl－将增加AMT在青铜表面上的吸附.

SERS Study on Adsorption of AMT on Bronze
Abstract:
New aspects of molecular interaction in corrosion inhibition are firstly reported in this investigation of 2-amino-5-mercapto-1,3,4-thiadiazole (AMT) on bronze using surface enhanced Raman scattering (SERS). The adsorption on bronze of the corrosion inhibitors 2-amino-5-mercapto-1，3，4-thiadiazole has been characterized in the AMT solution with and without Cl－ using electrochemical techniques and surface enhanced Raman spectroscopy. AMT is adsorbed in a perpendicular position at a given concentration. Cl－ and AMT are strongly coadsorbed on the surface of bronze in the presence of Cl－.
