　　采用中空纤维支撑乳化液膜非分散提取工艺，对所构建的乳化液膜体系OP-4/流动载体/液体石蜡/煤油/盐酸进行 In(Ⅲ)的提取研究，考察了流动载体、乳化剂 OP-4浓度、内相盐酸浓度、料液/乳液流速比等因素对提取结果的影响，计算了膜的渗透通量和渗透系数。结果表明：在所考察的三种流动载体 P204[二(2-乙基己基)磷酸]、P507[二(2-乙基己基-单-乙基己基)磷酸]、TBP(磷酸三丁酯)中，P204对In(Ⅲ)的提取效果最好；随着乳化剂OP-4浓度增大，提取率降低；内相盐酸浓度为2 mol×L-1时提取率最高，达到99.6%；料液/乳液流速比越大，提取率越低；膜的渗透通量和渗透系数随着料液/乳液流速比的增大而增大。在含杂质 Fe(Ⅲ)、Zn(Ⅱ)、Cu(Ⅱ)的料液中，各离子提取率大小顺序为In(Ⅲ)(81.5%)＞Fe(Ⅲ)(71.9%)＞Zn(Ⅱ)(25.3%)＞Cu(Ⅱ)(3.4%)，表明Fe(Ⅲ)对In(Ⅲ)的提取有较大影响。

A non-dispersive extraction technique with an emulsion liquid membrane supported by hollow-fiber-contactor was used for the extraction of In(Ⅲ) from the dilute feed aqueous. The emulsion system is consisted of OP-4/mobile carrier/kerosene/paraffin/HCl solution, in which the OP-4 acts as emulsifier. The influences of some factors, such as species of mobile carriers, OP-4 concentrations, HCl solution concentrations and flow rate ratio of feed to emulsion, on the extraction were studied, both the permeation flux and permeation coefficient were also calculated. Results reveal that, amount all the three mobile carriers P204, P507, TBP, the P204 shows the best extraction ability. The In(Ⅲ) extraction percentage decreases with the increase of OP-4 concentration and flow rate ratios of feed to emulsion, while the HCl solution concentration is 2 mol×L-1, the In(Ⅲ) extraction percentage reaches a highest value of 99.6%. Meanwhile, the permeation flux and permeation coefficient increase with the increase of flow rate ratios of feed to emulsion. When this technique was applied to extract In(Ⅲ) from a simulated feed liquid containing In(Ⅲ) and impurity ions of Fe(Ⅲ)、Zn(Ⅱ) and Cu(Ⅱ), the ion extraction percentages are in the order of In(Ⅲ)(81.5%)>Fe(Ⅲ)(71.9%)>Zn(Ⅱ)(25.3%)>Cu(Ⅱ)(3.4%), which shows that Fe(Ⅲ) has an obvious influence on In(Ⅲ) extraction.
