中文摘要：

以HZ-818大孔吸附树脂为载体，甲基三辛基氯化铵（N263）为萃取剂，利用干浸渍方法制备了N263浸渍树脂。采用静态吸附法考察了在盐酸体系中盐酸浓度、金属离子浓度、温度以及时问等因素对制备的浸渍树脂吸附分离In3＋、Fe3＋性能的影响。结果表明，浸渍树脂吸附In3＋、Fe3＋的最佳盐酸浓度均为4tool／L；其吸附In3＋、Fe3＋的等温吸附曲线符合Langmuir等温吸附模型；298K下对Fen、In3＋的饱和吸附容量分别为43．42mg／g、14．53mg／g。动力学研究表明，298K下浸渍树脂吸附Fe3＋、In3＋的平衡时间分别为6ll、10h。；仁二级动力学方程可较好地描述浸渍树脂对In03＋、FE3＋的吸附行为。混合体系中，浸渍树脂对Fe3＋表现出较好的吸附性能，而对ln3＋基本上不吸附，从而达到了初步分离In3＋、Fe3＋的目的。

英文摘要：

The impregnated resin was prepared by a dry-impregnation technique using HZ-818 macroreticular resin as the supporter and methyl trioctyl ammonium chloride （N263） as the extractant. The effects of the concentration of hydrochloric acid, concentration of metal ions, temperature and adsorption time on the adsorption and separation performance of In3＋and Fe3＋ from hydrochloric acid medium was studied with this impregnated resin by static adsorption method. Results showed that the optimized concentration of hydrochloric acid for adsorption of In3＋ and Fe3＋ were 4mol/L. The adsorption isotherms for In3＋ and Fe3＋ fitted Langmuir adsorption isotherm models. The maximum adsorption capacities for Fe3＋ and /n3＋ were 43.42mg/g and 14.53mg/g at 298K, respectively. The equilibrium time was 6h for Fe3＋ and 10h for In3＋. Kinetic data indicated that the adsorption for Fe3~ and In3~ with the impregnated resin agreed with the Pseudo-second-order rate equation. In binary components solution, the impregnated resins were with better selective adsorption for Fe3＋ but no adsorption for Ina＋. The preliminary separation of In3＋ and Fe~＋ was achieved.
