| 摘 要： | The effect of different anion on the morphology of electrode, the adsorption of quinoline and the SER spectra are investigeted. The adsorption peak of quinoline appears in cyclic voltammogram in Cl~- (or Br~-) -containing electrolyte, but not in NV_3~- solution. We also find that the adsorption of quinoline is correlated with Cl~- concentration. This indicates some complex consist of Cl~- and quinolne are produced on Ag surface, Scanning electron microscopy is used to evaluate differences in surface morphology subjected to ORC treatment in different anion solution.The surface morphology of Aq electrode roughened in NO_3~- solution on which no SER signal can be observed differs greatly from that of Ag electrode which roughened in Cl~-(or Br~-)-containing electrolyte.
