摘要
研究了由４，４′－癸二酰－双－（１－苯基－３－甲基－５－吡唑啉酮）（ＤＢＰＭＰ，简作Ｈ２Ａ），氧化三辛基膦（ＴＯＰＯ），吡啶（Ｐｙ）组成的三元体系从硝酸溶液中对铀（Ⅵ）的协同萃取，斜率法确定萃合物组成为ＵＯ２Ａ·ＴＯＰＯ·Ｐｙ，制取了固体协萃配合物，并用元素分析、ＩＲ及￣１ＨＮＭＲ等进行了表征。
The synergistic extraction of uranitim(Ⅵ)by a ternary system composed of 4, 4′-decanedioyl-bis-(1- phenyl-3-methyl-5-pyrazolone),trioctylphosphine oxide(TOPO)andpyridine was studied.The composition of the extracted compound in solution was determinedusing the slope method.The extracted solid termary complex was characterized by means ofelemental analysis,IR and 1H NMR preliminarily.
