把含LIX64N10(体积)％的煤油溶液与含Fe(Ⅲ)2克/升的同体积的铁明矾溶液,在折流式烧杯中,于pH2.05时搅拌混合,温度保持室温,各相取样时间均在间隔20及163小时。在试验周期中,有机相中的含铁量为0.25及0.30克/升,无上升迹象,说明在20小时内已达到平衡。用含Cu0.156克/升的酸性硫酸铜溶液, The Lix64N10 (volume)% kerosene solution containing Fe (Ⅲ) 2 g / l with the same volume of iron alum solution in a baffled beaker, stirring at pH 2.05 when the mixing temperature was maintained at room temperature, each phase sampling The time is at intervals of 20 and 163 hours. During the test period, the iron content in the organic phase was 0.25 and 0.30 g / L with no sign of ascent, indicating that equilibrium was reached within 20 hours. With Cu0.156 g / liter of acidic copper sulfate solution,
