LLX separation of carrier-free 47Sc, 48V and 48,49,51Cr produced in α-particle activated titanium with HDEHP

A LLX procedure for carrier-free separation of the radioisotopes, 47Sc, 48V and 48,49,51Cr, the 40 MeV α-particle activation products of titanium has been developed. Sequential separations of the radionuclides produced in the titanium matrix through the nuclear reactions (α, α pxn), (α, pxn) and (α, xn) have been performed through LLX from aqueous H2SO4 and HClO4 acid media using the liquid cation exchanger, HDEHP, as an extractant. Purity of the carrier-free radiotracers at different stages of their separations has been verified by γ-ray spectrometry.
