摘要
Surface enhanced raman spectrosscopy (SERS)has been used to studey the electrochemical coadsorption of TU at silver electrodes in solutions containing nitric acid ,sulphuric acid and perchloric acid respectively or any two of them.It was found that these different anions can be induce-coadsorbed simultaneously on the silver surface through the protonated amino group of TU in the mixed acids ysstem.The coadsorption ability of the anions are in the order of So>NO?CLO at the potentials of at the potentials of The stability of TU on the surface of Agelectrode depends not only on the electrode potential but also on the nature of electrolyte anions coadsopbed.
