ABSTRACT:
Halide-free rhodium nitrate is produced by a process which comprises quantitative reaction of metallic rhodium with hydrochloric acid, gaseous chloride and gaseous hydrogen chloride to produce hexachlororhodic acid, followed by the quantitative reaction of this acid with potassium iodide to produce rhodium iodide. The resulting rhodium iodide is quantitatively converted to halide-free rhodium nitrate by reacting with nitric acid and hydrogen peroxide.
