The Separation and Fluorescent X-Ray Spectrometric Determination of Zirconium, Molybdenum, Ruthenium, Rhodium, and Palladium in Solution in Uranium-Base Fissium Alloys.
The various elements are separated prior to the fluorescent x-ray determination because of either direct x-ray line interference or negative interference to the characteristic x-ray intensities caused by the presence of the other elements in the solution. Palladium is precipitated with dimethylglyoxime, and the precipitate is extracted with chloroform. The aqueous portion is made 6M in hydrochloric acid and is passed through a Dowex 1-X8 anion exchange resin. Zirconium and rhodium do not adsorb, uranium is eluted with 0.3M hydrochloric acid, ruthenium and molybdenum are eluted with 8M nitric acid. The various elements are then determined by counting their K alpha radiation using a lithium fluoride plane crystal for dispersion. (auth)
