2,6-双[(1-苯基-3-甲基-5-氧-4-吡唑啉基)甲酰基]吡啶对铀的液液萃取

Liquid Liquid Extraction of Uranyl with 2,6 Bis(4 Carbobyl) (1 Phenyl 3 Methyl 5 Oxo Pyrazolinyl) Pyridine

研究了新型双β二酮萃取剂２，６－双［（１－苯基－３－甲基－５－氧－４－吡唑啉基甲酰基）］吡啶（ＰＤＣＢＰ，简称Ｈ２Ａ）的氯仿溶液对铀酰的萃取行为，所得萃合物组成为ＵＯ２（ＨＡ）２．比较了Ｈ２Ａ对ＵＯ２＋２、ＲＥ３＋、Ｔｈ（Ⅳ）、Ｚｒ（Ⅳ）、Ｈｆ（Ⅳ）等１１种元素的分离因子，并讨论了ＵＯ２（ＨＡ）２的谱学性质．

In this paper, the extraction behavior of uranyl with 2,6 bis[4 carbobyl(1 phenyl 3 methyl 5 oxo pyrazolinyl)]pyridine has been investigated. The composition of the extracted complex is UO 2(HA) 2. The separation factors of UO 2+ 2 have been compared to the other eleven elements (e.g. RE. Th(Ⅳ). Zr(Ⅳ). Hf(Ⅳ) etc.). And the spectroscopy properties of the UO 2(HA) 2 have been discussed.
