摘要

本文首次研究了新型酰胺萃取剂N -癸酰基吗啡啉（DMPHL） /苯体系在硝酸介质中对U（Ⅵ ）的萃取性能

考察了硝酸浓度、萃取剂浓度等因素对U（Ⅵ ）萃取性能的影响

初步研究了标题萃取剂对硝酸及U（Ⅵ ）的萃取机理。认为标题萃取剂与硝酸形成单分子配合物

与U（Ⅵ ）配合物的组成为UO2 （NO3） 2 ·2DMPHL。同时发现

萃取U（Ⅵ ）时最大分配比所对应的酸度高于一般的单酰胺

说明该萃取剂适合于高酸度下操作。

Abstract

N-Decanoylmorpholine has been used as novel extractant for HNO 3 and U(Ⅵ) in benzene from aqueous nitric acid medium for the first time. The dependence of extraction distribution ratio on the concentration of aqueous nitric acid and extractant was discussed. The extraction mechanisms of HNO 3 and U(Ⅵ) were confirmed. DMPHL was found suitable for extraction of U(Ⅵ) at high acidity.
