摘要
An operational modification of Tafel analysis, applied to the intermediate region of square wave voltammetric curves, devoted to the identification of corrosion products on archaeological metal, is described. This is based on the voltammetry of microparticles methodology using conventional abrasive conditioning of the electrode, as well as one-touch and layer-by-layer techniques. The proposed methodology is applied to the identification of copper and silver corrosion products in mediaeval silver-copper coins from the Libertad street hoard in Valencia (Spain).
