【摘要】 利用分子谱学表征手段,研究了微乳相萃取分离锑和铁选择性产生的微观机制。试验发现,锑和铁的萃取分离与微乳相反胶束微水池内形成"超浓盐酸"特殊微观介质环境有关。由于大量聚集的HCl参与配位,反胶束内锑和铁的配位行为及相对含量发生变化,导致锑和铁萃取分离。更多还原

【Abstract】 The mechanism of separation between Fe and Sb by microcmulsion extraction was investigated.It was found that the separation between Fe and Sb was connected with formation of an ultra-concentrated hydrochloric acid in microemulsion phases. The large amount of HCl molecules concentrated in nanoscopic water-pool of micelles participates forming complexes such as HmSbClnz+.It was the difference in coordination behavior of Fe and Sb in microemulsion phase that resulted in extraction separation between Fe and Sb.更多还原
