TRPO中Am~(3+),Pu(Ⅳ),UO_2~(2+),TcO_4~-的反萃及其红外光谱和裂解色谱分析

BACK-EXTRACTION OF Am~(3+),Pu(Ⅳ), UO_2~(2+) AND TcO_4~-FROM DIFFERENT TRPO AND IR AND PYROGRAPHY ANALYSIS OF THE TRPO

摘要: 研究了硝酸、草酸、碳酸钠和碳酸铵对 4种不同来源的TRPO/煤油中Am3 + ,Pu(IV) ,UO2 2 + 和TcO-4的反萃 ,观察了碳酸钠溶液反萃铀时的乳化现象 ,比较了上述 4种TRPO的红外光谱、裂解色谱。结果表明 ,不同来源的TRPO具有相似的基团 ,但组成有差别

Abstract: The back extraction of Am 3+ ,Pu(IV),UO 2+ 2 and TcO - 4 with high concentration nitric acid, oxalic acid, sodium carbonate, ammonium carbonate respectively from different 30% TRPO/kerosene systems are studied. The emulsification phenomenon during the back extraction of UO 2+ 2 with sodium carbonate is investigated. The infrared sorption spectra and the pyrography of these TRPOs are compared. The results show that different TRPOs have same kinds of base groups, but have different constitution of these base groups.
