Uranium is extracted with 30% tributyl phosphate in carbon tetrachloride from a nitric acid solution of the fissium alloy which contains ursnium, molybdenum, ruthenium, palladium, and zirconium, and the raffinate is strongly fumed with perchloric acid. The solution is then passed through a Dowex 50W-X8 cation exchange resin. Palladium is eluted with 0.3M hydrochloric acid, and the rhodium is then eluted with 6M hydrochloric acid. Rhodium is determined spectrophotometrically with tin(II) chloride.
