Abstract
A rapid radiochemical separation procedure has been finished by using of radiochemical separation and γ-spectrum measurement methods. In this isolation procedure, tantalum nuclides produced by the irradiation of natural tungsten targets with 14 MeV neutrons were extracted by methyl isobutyl ketone (MIBK) in the system of HF-HNO3 mixed solutions. It has been found that tantalum was rapidly and efficiently separated in the isolation procedure and the decontamination factors of tungsten were more than 104. The procedure is simultaneously used to separate tantalum from tungsten bombarded with intermediate energy (47 MeV/u)18O beams. The measured γ-spectra showed that tantalum can be separated from most elements produced in the nuclear reactions except for a few elements.
