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 mechanism of extraction of uranyl sulfate from n-heptane solution of primary amine N_ (1923) from sulfuric acid medium was studied. It was considered that the sulfate of primary amine N_ (1923) formed reverse micelles (or micelles) in the organic phase, And confirmed by infrared spectroscopy and transmission electron microscopy.The extraction of primary amine N_ (1923) and uranyl mainly exist in the reverse micelle phase.The experimental facts which can not be explained by the slope method can be well explained.
