The dissolution of platinum from platinum iron alloys in oxygenated hydrochloric acid/sodium chloride solutions has been investigated using an autoclave technique.
The dissolution rate was found to be dependent on alloy composition, acid concentration, and oxygen pressure. The dissolution followed typical corrosion kinetics and analysis of the results indicated that the cathodic reduction of oxygen was the rate controlling step in the dissolution reaction, at high chloride ion concentrations. An apparent activation energy of 16.8 kcal per mold was found for the dissolution of PtFe alloys, and 19 kcal per mole for pure Pt sheet. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
