抄録
In order to utilize a 211At isotope, a promising α-emitter for radionuclide therapy, the chemical properties of astatine isotopes are studied. We have examined wet chemistry methods through the distribution ratios of astatine in liquid–liquid extraction. The astatine isotopes have been found to be well extracted into DIPE and MIBK. We observed that the distribution ratio of astatine isotopes increases with concentrations of HCl greater than 3 M, while it decreases with the HCl concentration less than 2 M. The results will be useful for development of the 211Rn–211At generator.
