摘要
应用ＵＦ６水解模拟液ＵＦ２Ｏ２＋４ＨＦ与ＮＨ３水反应研究了ＡＤＵ的沉淀过程，研究结果认为，ＡＤＵ的沉淀过程可分为：中和阶段、ＡＵＦ［（ＮＨ４）３ＵＯ２Ｆ５］生成阶段、ＡＤＵ生成阶段。并对中间化合物ＡＵＦ结晶生成规律，化学组成等进行了研究。详细讨论了一些重要工艺条件对ＡＤＵ生成条件及特性的影响。
ADU precipitation is studied by potentiometric
titration of UO 2F 2+4HF with ammonia. It is found that the ADU precipitation process consists
of neutralization, formation of AUF and formation of ADU. The formation conditions, the chemical
composition and the microstructure of intermediate product AUF crystal are researched. The
effects of some important technological parameters on the chemical composition and
microstructure of the ADU precipitate are discussed.
