摘要：
The present invention describes a method for purification of 225Ac from irradiated 226Ra-targets provided on a support comprising a leaching treatment of the 225Ra-targets for leaching essentially for the entirety of 223Ac and 226Ra with nitric or hydrochloric acid, followed by a first extraction chromatography for separating 225Ac from 226Ra and other Ra-isotops and a second extraction chromotography for separating 225Ac from 210Po and 210Pb. The finally purified 225Ac can be used to prepare compositions useful for pharmaceutical purposes.
