摘要：

The effect of a roughening procedure on surface-enhanced Raman scattering (SERS) intensity of pyridine at copper and gold electrodes subjected to negative potential has been investigated. Among four procedures tested for a copper electrode the one consisting of electrochemical activation in a solution of LiCl and CuCl2 resulted in the most stable and effective surface. It was proved that the presence of pyridine during the pretreatment procedure caused a very fast, irreversible decay of SERS intensity for both copper and gold electrodes. Quite stable, at least at room temperatures, gold surfaces were obtained by oxidation-reduction cycles activation in KCl solution.
