2－羟基－5－烷基苯乙肟萃取Am^（3＋）和镧系元素行为的研究Ⅱ．配合物结构与萃取机理的分析

STUDIES OF THE EXTRACTION BEHAVIOR OF Am￣(3+) AND LANTHANIDES WITH 7804 EXTRACTANT Ⅱ.COMPLEX STRUCTURE AND ANALYSIS OF EXTRACTION MECHANISM

测量了２－羟基－５－烷基苯乙肟（７８０４）萃取Ｎｄ￣（３＋）的萃取配合物红外谱图、ｆ元素的超灵敏跃迁光谱及萃取剂的稀释效应红外谱图。推断了萃取配合物的结构、萃取机理，计算了镅及一些镧系元素的萃取平衡常数。

The IR and hypersensitive spectra of the complex Nd￣(3+)-7804 and the diluting IR spectrumof 7804 extractant are measured.The complex structure is deduced and the extraction mechanismis discussed.The extraction equilibrium constants of americium and lanthanides are calculated.
