摘　　要：利用共焦显微拉曼系统研究了乙醇溶剂中2 巯基苯并噻唑(HMBT)在不同pH条件下吸附在ORC法粗糙化处理所得铁表面的SERS光谱。结果表明2 巯基苯并噻唑分子在酸性和中性溶液中通过环外S或环内N原子吸附于铁表面,而在碱性溶液中分子失去氢原子,并通过静电相互作用吸附于铁表面上。The Surface Enhanced Raman Spectra of 2Mercaptobenzothiazole (HMBT) adsorbed on the surface of an ORCetched iron electrode in ethanol solvent were obtained. The results show that the molecules were adsorbed onto the iron electrode via its exocyclic S atom in a basic solution of pH 13 and its exocyclic S atom or N atom on the thiazole ring in an acidic solution of pH 3.
