In order to determine the influence of anions on anodic passivation of zirconium in solution of certain salts, experiments were made with zirconium iodide in 1 N aqueous solutions of KCl, KNO/sub 3/, K/sub 2/SO/sub 4/, KH/sub 2/PO/sub 4/ + K/sub 2/HPO/sub 4/ at constant pH. The potentials are given relative to a silver chloride electrode. The data show that the formation of an anodic film on zirconium is characterized by a continuous decrease in the capacitative impedance and an increase in the ohmic component. Anodically oxidized zirconium depends on the anionic composition of the solutions.
