摘要
研究了伯胺N_(1923)的正庚烷溶液从硫酸介质中萃取硫酸铀酰的机理.认为伯胺N_(1923)的硫酸盐在有机相中形成了反向胶束(或胶团),并由红外光谱和透射电镜佐证.伯胺N_(1923)和铀酰形成的萃合物主要存在于反向胶束准相中.可以较好地解释用斜率法无法解释的实验事实.
The extraction mechanism of uranium( VI) from sulfuric acid media by primary amineN1923 is investigated. The suggestion that the ammonium salt forms the reversed micelle or microemulsion due to aggregation is proved by infrared spectra and TEM images. The extraction compound exists mainly in the reversed micelle pseudophase. This mechanism can be used for explicating the experimental results, which can not be explained by the conventional slope method.
