| 摘 要： | 系统地研究了2－乙基己氧基甲基磷酸二（2－乙基己基）酯（代号PT－28）对硫酸、磷酸、硝酸、高氯酸、盐酸和醋酸六种酸的萃取行为，发现PT－28对硫酸、磷酸、盐酸和醋酸均不萃取，只对硝酸和醋酸萃取，这与中性磷氧萃取剂甲基膦酸二甲庚酯（P350）和磷酸三正丁酯（TBP）对强酸的萃取有显著的不同，并对其萃取机理进行了讨论。 |
| 关 键 词： | PT－28 萃取 无机酸 有机酸 萃取剂 |

| Abstract: | The behaviors and mechanisms of 2-ethyl hexoxyyl methyl Phosphoric acid (2-ethylhexyl) ester (code name PT-28) extracting sulphuric acid, phosphoric acid, nitric acid, high chloric acid, hydrochloric acid and ethanoic acid were studied systematically in this paper. It was found that PT-28 can not extract H2SO4, H3PO4, HClO4, and HCl, but extract HNO3 and HAc, because PT-28 is very different from the other neutral phosphine oxygen extractant (P350 and TBP) in the aspect of extracting mineral acid, and its mechanism was discussed. |
| Keywords: | PT-28 extract inorganic acid organic acid. |
