摘要： The invention is directed to a method for the purification of Radium, in particular 226Ra, for target preparation for an essentially pure 225Ac production from available radioactive sources, using an extraction chromatography in order to separate chemically similar elements such as Ba, Sr, and Pb from the desired Ra; wherein said extraction chromatography has an extractant system on the basis of a crown ether. The invention is related to a method for recycling of 226Ra, for target preparation for 225Ac production from radium sources irradiated with accelerated protons (p,2n), after separation of the produced 225Ac. In this method a combination of the above extraction chromatography and a cation exchange chromatography is used. The obtained 226Ra is essentially free of the following chemical contaminants consisting of Ag, Al, As, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Sr, V, Zn, and Ba.
摘要翻译：本发明涉及一种用于纯化镭（特别是226Ra）的方法，用于使用提取色谱从化学上类似的元素如Ba，Sr和Pb分离用于从可用的放射源制备基本上纯的225Ac产物的目标制备从所需的Ra; 其中所述提取色谱法具有基于冠醚的萃取剂体系。本发明涉及一种用于回收226Ra的方法，用于在分离产生的225Ac之后，用加速质子（p，2n）照射的镭源进行225Ac生产的目标制备。在该方法中，使用上述提取色谱和阳离子交换层析的组合。得到的226Ra基本上不含由Ag，Al，As，Be，Bi，Ca，Cd，Co，Cr，Cu，Fe，Ga，K，Li，Mg，Mn，Na，Ni，Pb组成的以下化学污染物，Sr，V，Zn和Ba。
