摘要

The objective of the present invention is to separate a metal RI in a short time.A separating device 3 for separating a radioisotope (RI) from a first solution containing a metal and the RI, obtained by transformation of the metal, is provided with an electrode 31 for applying a prescribed voltage to the first solution, wherein the prescribed voltage is a voltage with which a rate of electrodeposition of the metal onto the electrode 31 is different from the rate of electrodeposition of the RI onto the electrode 31.
