Abstract
Irradiation of natural lutetium oxide target with 7Li beam results in the formation of no-carrier-added 177W radionuclide in the matrix. An efficient radiochemical procedure for the separation of no-carrier-added (nca) 177W (T 1/2 = 2.21 h) radionuclide is presented using liquid-liquid extraction (LLX). A high separation factor between nca 177W from the target Lu has been achieved with 0.1 M TOA and 8 M HCl. About 85% of 177W has been extracted in the organic phase keeping Lu in the aqueous phase in a single run. Using this production and separation method radiochemically pure 177W can be obtained. The separation has also been tried with a greener approach viz. aqueous biphasic extraction. In this case, aqueous biphasic extraction is not a good method for separation of 177W. The radionuclide 177W thus obtained can be used to study the extraction pattern of lighter homologue of the element 106 (Sg) together with Mo, which in turn is important to investigate the chemistry of Sg.
