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.

Abstract: 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) and pyridine 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.

Key words: uranium(Ⅵ), ternary synergistic extraction, decanedioyl-bis-(phenyl-methyl-pyrazolone), trioctylphosphiiie oxide, pyridine
