Liquid-liquid extraction of carrier-free radioisotopes produced in α-particle activated molybdenum target by HDEHP and TBP

Simultaneous production of carrier free isotopes like 95,96Nb, 93,94,95,96,99mTc and 94,95,97,103Ru through the nuclear reactions (α, αpxn), (α, pxn) and (α, xn) has been performed by α-particle activation of a molybdenum target. The sequential separation of the produced radioisotopes from the bulk target matrix has been achieved through LLX using HDEHP and TBP as liquid exchangers. Formation of the carrier free radionuclides in the target matrix and their purity in different stages of separation have been verified by taking recourse to γ-ray spectrometry.
