INORGANIC EXTRACTION STUDIES ON THE SYSTEM ALKYLAMINE-NITRIC ACID. AMBERLITE LA-1 AND TRI-ISO-OCTYLAMINE

Journal Article · · Nippon Genshiryoku Oakkaishi
OSTI ID:4743037
The solvent extraction behavior of about sixty chemical elements was extensively surveyed in the alkylamine-nitric acid system, clarifying radiochemically the acid dependence of distribution ratios. The organic phases used were 10% (V/V) Amberlite LA-1 and 5% (V/V) tri-iso-octylamine xylene solution. The highly extractable chemical species were not so many in number through two extraction systems. In most cases the acid dependence curves of a given element were not only similar to each other between the two systems, but also resembled that in 10D% TBP-HNO/sub 3/ system. The exceptional high K/sub d/ value of technetium at 1 N HNO/sub 3/ suggested an application to separating Tc/ sup 99m/ from neutron-irradiated ammonium molybdate. (auth)
