锝的TBP萃取化学行为研究

摘要

摘要: 报道了在硝酸体系中用３０％ＴＢＰ－正十二烷萃取Ｔｃ（Ⅶ）的实验结果。详细研究了硝酸、硝酸铀酰、硝酸铀（Ⅳ）、硝酸铵、亚硝酸钠、硝酸锆、硝酸钚、硝酸铈，亚硝酰钌、硝酸羟胺、硝酸肼浓度及温度、相比等因素对Ｔｃ（Ⅶ）萃取化学行为的影响。实验结果表明，在不含铀的硝酸体系中，硝酸、硝酸铵、硝酸钚、硝酸锆、硝酸铈、亚硝酸酰钌浓度及萃取温度对Ｔｃ（Ⅶ）的分配比影响很大，而亚硝酸钠、硝酸肼及硝酸羟胺浓度对Ｔｃ（Ⅶ）的分配比影响较小；在含铀的硝酸体系中，硝酸浓度对Ｔｃ（Ⅶ）的分配比有影响，而萃取温度、硝酸钚、锆的影响较小。Ｔｃ（Ⅶ）在含或不含铀的硝酸体系中，与ＴＢＰ分别形成ＵＯ２ＮＯ３·ＴｃＯ４·２ＴＢＰ和ＨＴｃＯ４·３ＴＢＰ萃合物。
