This method was developed for the determination of zirconium in plutonium--uranium-"fissium" alloys. A sample of the alloy containing 40 to 100 - g of zirconium in 10N nitric acid was separated from plutonium and from some of the palladium by anion exchange. The effluent was analyzed for plutonium since more than 60 - g would interfere. The ruthenium was removed by fuming with perchloric acid. The uranium and molybdenum do not interfere in reasonable quantities as they exist in this alloy. The alizarin redS lake was formed in 0.1N nitric acid, and its absorbancy was measured by means of the Beckman Model B spectrophotometer at 520 m - . The color was stable for several hr and reproducible within 3 to 5% of the amount present. The interference of the alloying constituents and reagents is given. The time required for duplicate analyses was about 31/2 hr, and the equipment and techniques used are standard. (auth)
