S25  Métodos Numéricos    Titulo: NUMERICAL SIMULATION OF THE ANODIC DISSOLUTION OF ZINC   Resumo : ABSTRACT: A MATHEMATICAL MODEL OF ANODIC DISSOLUTION OF ZINC IN ORGANIC SOLVENTS WAS DEVELOPED. NUMERICAL ANALYSIS IS PERFORMED USING THIS MODEL TO SIMULATE THE KINETICS OF THE ELECTROCHEMICAL REACTION. THE MECHANISM AND KINETIC OF ANODIC DISSOLUTION OF ZINC WERE EXAMINED IN PROTOGENIC (METHANOL) AND APROTIC (ACETONITRILE) SOLVENTS CONTAINING LICLO4 AS A BASIC ELECTROLYTE. RESULT OF THAT RESEARCH ALLOWED TO GIVE THE MECHANISM OF ANODIC DISSOLUTION OF ZINC IN ANHYDROUS ORGANIC MEDIA. DESORPTION OF INTERMEDIATE PRODUCT - ZN+AD OCCURRING ON ENERGETICALLY PREFERENCE PLACES OF ZINC SURFACE (KINKS, STRUCTURAL DEFECTS) PLAYS A VERY IMPORTANT ROLE IN THIS MECHANISM. THE DESORPTION PROCEEDS ACCORDING TO CATALYTIC PROCESS SIMILAR TO THE HEUSLER MECHANISM FOR METALS OF IRON GROUP. EXPERIMENTAL INVESTIGATION CONFIRMS THE SIMULATION RESULTS.
