【摘要】 以Ｎ－己基异辛酰胺作为Ｉｒ（Ⅳ）的新型萃取剂用于Ｒｈ、Ｉｒ分离，考察不同稀释剂的分相情况，有机相组成对萃取率的影响。选择ＴＢＰ－正辛烷作有机相稀释剂，考察水相介质中Ｈ＋、Ｃｌ－浓度以及Ｃｕ２＋、Ｆｅ３＋、Ｎｉ２＋的萃取行为。结果认为水是最有效的反萃剂更多还原

【Abstract】 N-hexyl isooctylamide was used as an extractant of Ir(Ⅳ)for separation from Rh. The influence of thinner on phase separation and of components in organic phase on the extraction has been investigated. Under selecting TBP-octane as a thinner, the influence of H +, Cl - ions concentration in aqueous medium on the extraction, and extractive behaviour of Cu 2+ ,Fe 3+ ,Ni 2+ ions have been investigated. The water was the most efficient stripping agent.更多还原
