A SERS SPECTRA STUDY OF N-HETEROCYCLE INHIBITOR ON NON-SERS ACTIVE METAL IRON

This paper presents the SERS spectra of quinoline adsorbed on iron deposited on the silver electrode by the cathodic reaction of ferrousion. Adsorption and inhibition mechanism of quinoline were discussed by means of the SERS spectra.     

THE EFFECT OF ANION ON THE MORPHOLOGY OF ELECTRODE, THE ADSORPTION OF QUINOLINE AND THE SER SPECTRA

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.     

THE EFFECT OF ANION ON THE MORPHOLOGY OF ELECTRODE, THE ADSORPTION OF QUINOLINE AND THE SER SPECTRA

The effect of different anion on the morphology of electrode,the adsorption of quinoline and the SER spectra are investigented.The adsortion peak of quinoline appears in cyclic voliammogram in Cl^-(or Br^-) -containing electrolyte,but not in NO3^- solution.We also find that the adsorption of quinoline is correlated with Cl^- concentration.This indicates some complex consity of Cl^- and quinolue are produced on Ag surface.Scanning electron microscopy is used to evaluute differences in surface morphology subjected to ORC treatment in different anion solution.The surjace morphology of Ag elecirode roughened in NO3^- solution on which no SER signal can be lbserved differs greatly from that of Ag electrode which roughened in Cl^-(or Br^-)-containing clectrolyte.
