Electrochemical method for producing
radionuclide Lu-177 with high specific activity
Abstract
The modified method of the isolation of
radionuclide 177Lu obtained from irradiated by thermal neutrons
Yb-176 target is proposed. The method consists of the combination of two
electrochemical processes – cementation of ytterbium acetate-chloride solution
to the sodium amalgam and subsequent electrolysis of ytterbium solution in
separate electrolytic cell without adjusting the solution. The electrochemical
set-up consisting of 2 cells gave the purification factor of 177Lu
from ytterbium at level of 105–106, which allows using 177Lu
of such quality for labeling bioorganic molecules.
Key words: NCA 177-lutetium, ytterbium-169,
cementation, electrolysis with mercury cathode, the electrochemical cleaning
method, separation of radionuclides.
