摘要
对ＭＮＡ－ＴＢＰ从盐酸介质中萃取Ｉｒ（Ⅳ）作了研究．结果表明：ＭＮＡ－ＴＢＰ对Ｉｒ（Ⅳ）萃取有协同效应．当ＭＮＡ和ＴＢＰ在正辛烷中的浓度各为０．４５ｍｏｌ／Ｌ，待萃液中ＨＣｌ总浓度为４ｍｏｌ／Ｌ，铱浓度为１７３．１３μｇ／ｍｌ，相比为１时，协萃系数Ｒ为２．３３，协萃合物的组成为（ＭＮＡＨ）＋．ＩｒＣｌ＄２－６．（ＨＴＢＰ）＋．
Extraction of Ir(IV) from HCl medium with MNA (N-hexy1 isooctylamine)-TBP (Tributyl phosphate)is studied. The results show that there is synergism in this system.When (o) = (o) =0.45 mol/L in octane solvent,=4 mol/L and =173.13 μg/ml in original aqueous phase and O/A=1:1, the ratio of synergism is 2.33. The composition of synergistic complex is found to be +.IrCl 2- 6. +.
