Abstract: Using surface enhanced Raman scattering(SERS)and time resolved surface enhanced Raman scattering(TRSERS)spectroscopies, the electrochemical coadsorption of 1-allyl-2-thiourea(ATU)with one or two kinds of eletrolyte anions at sliver electrodes in perchloric acid, sulphuric acid, nitric acid medium respectively has been studied. The orientation of ATU on the surface was proposed. The results indicate that these anions can be coadsorbed on the electrode, induced by the protonated amino groups of ATU surface. The order of the coadsorption with ATU was found to be: ClO4->SO42->NO3-.

Key words: allylthiourea, electrolyte anion, coadsorption, silver electrode, SERS
