Abstract
A method for producing 225including: a method (X) for purifying aRa-containing solution, including an adsorption step of allowing aRa ion to adsorb onto a carrier having a function of selectively adsorbing a divalent cation by bringing aRa-containing solution into contact with the carrier under an alkaline condition, and an elution step of eluting theRa ion from the carrier under an acidic condition; a method for producing aRa target, including an electrodeposition liquid preparation step of preparing an electrodeposition liquid by using a purifiedRa-containing solution obtained by the method (X), and an electrodeposition step of electrodepositing aRa-containing substance on a substrate by using the electrodeposition liquid; and a step of irradiating aRa target produced by the method for producing aRa target with at least one selected from a charged particle, a photon, and a neutron by using an accelerator.
