Chemical research quarterly report, October through December 1952
Progress is reported on the work performed during the quarter by Chemical Research, Separations Technology Unit. The report covers process work performed on the Uranium Recovery Process, distribution of metal-ion impurities (in both the Redox and Uranium Recovery Processes), a second plutonium cycle for the Purex Process using reflux to obtain added decontamination and a concentrated product, and the Recuplex Process. Process improvement studies are reported on the effect of dissolving conditions on fission-product behavior during solvent extraction, extraction from hydrochloric acid solutions, scavenging ruthenium activity with mercaptans, production of UO{sub 3} by calcining uranyl peroxide, and nitric acid recovery. Physical chemistry studies of solvent extraction included activity coefficients of TBP, solubility of TBP in water from various TBP-diluent solutions, self-diffusion of TBP, liquid-liquid dispersion studies and organophosphorus solvent studies. Ion exchange coupling investigations are reported. The effect of slag composition on reduction yields are given. Progress on fundamental ruthenium chemistry is reported. Waste treatment investigations included effect of decontaminating agents on the BiPO{sub 4} waste systems, solvent extraction of fission products, behavior of iodine in the Purex solvent and studies of emulsions and solids formed in Purex solvent recovery. 12 figs., 46 tabs.
