Abstract

By utilizing SERS (surface-enhanced Raman spectroscopy) technique and a confocal microprobe Raman system, the competitive adsorption of dimethylsulphoxide (DMSO) molecule or imidazole molecule was investigated in the acetonitrile solution at silver electrode.It was found that DMSO or imidazole molecule had more preferential adsorption than acetonitrile.This competitive adsorption significantly inhibits the decomposition reaction of acetonitrile.When the potential became more negative, DMSO or imidazole was desorbed gradually and the decomposition reaction of acetonitrile occurred.

Key words: surface enhanced Raman spectroscopy(SERS), non-aqueous system, acetonitrile, DMSO, imidazole
