Extraction with 1% TBP in toluene from 8-10N hydrochloric acid provides a nice method for the separation of zirconium and niobium from the slow neutron fission products of uranium.
(1) A synthetic mixture was prepared by adding ⁹⁵Zr-⁹⁵Nb into an old fission products solution. From the mixture, ⁹⁵Zr-⁹⁵Nb was recovered by 1% TBP extraction from 10N hydrochloric acid.
(2) The fission products of uranium, irradiated in JRR-1 for 2 hr and cooled for one day, was dissolved in 8N hydrochloric acid and shaken with 1% TBP. The zirconium and niobium extracted were stripped from the organic phase with 0.5N hydrochloric acid.
(3) Starting from a mixture of ⁹⁵Zr-⁹⁵Nb, ¹⁴¹Ce and small amounts of other fission products, ⁹⁵Zr-⁹⁵Nb was isolated by a similar extraction from 10N acid.
This method is supposed to be a handy method for the cleaning up of ⁹⁵Zr-⁹⁵Nb tracer.
