摘要
研究了 Ｔｗ ｅｅｎ８０－ 水杨基荧光酮（ Ｓ Ａ Ｆ）－ （ Ｎ Ｈ４）２ Ｓ Ｏ４ 体系萃取钼的行为及 Ｔｗ ｅｅｎ８０ 水溶液分相条件的选择．实验表明，在适当ｐ Ｈ 条件下，该体系能使 Ｍｏ（Ⅵ）与 Ｆｅ３＋ 、 Ｃｏ２＋ 、 Ｎｉ２＋ 、 Ｍｎ２＋ 、 Ｚｎ２＋ 、 Ｃｄ２＋ 、 Ｃｕ２＋
In the presence of various(NH 4) 2SO 4 the conditions of apueous Tween80 solution were stuide.The distribution behaviour of some metal ions with (NH 4) 2SO 4 between the liquid and solid phases was examined.With (NH 4) 2SO 4 as salting-out reagent.The quantitative extraction seperaption of Mo(Ⅱ)and Fe(Ⅲ)、Zn(Ⅱ)、Co(Ⅱ)、Cd(Ⅱ)、Cu(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ)was achived by controlling the solution acidity.The expermental results explained that the complex of Mo(Ⅵ) with SAF can be extracted into the Tween80 liquid phase.
