Corrosion of Ag-Ag2O in Iodide Solutions: A Potential Radioiodine Immobilization Route

Abstract

The reaction kinetics of Ag2O films on Ag with aqueous iodide forming AgI were followed by a novel method of monitoring open-circuit potential (EOC) under static and rotating conditions. The solid-liquid interfacial kinetic parameters can then be determined by measuring τƒ as a function of surface area of Ag2O and I− concentration. In this study, the application of the technique is extended to examine the effect of mass transport on the reaction kinetics by measuring τƒ as a function of electrode rotation rate.
