SERS Study of Adsorption and Condensation Reaction of Urea on Silver Electrode
Abstract:
Adsorption behavior of urea on silver electrode and the influence of thiourea on its adsorption in sulphuric acid solution were investigated by polarization curves and Surface Enhanced Raman Spectroscopy. Urea was found to under a condensation reaction on roughened silver electrode. Biuret was the condensation compound, and was adsorbed in the protonated form on the silver surface. Obvious synergistic mechanism between thiourea and protonated biuret was proposed.
