研究了大孔膦酸型树脂对铟(Ⅲ)的吸附、洗脱条件;不同金属离子对铟吸附的影响;树脂吸附铟的容量及配位比。并用化学分析法及红外光谱探讨了膦酸树脂吸附铟的机理。 The adsorption and elution conditions of indium (Ⅲ) by macroporous phosphonic acid resin were studied. The effects of different metal ions on the adsorption of indium and the capacity and coordination ratio of indium adsorbed by the resin were investigated. The mechanism of adsorption of indium by phosphonic acid resin was also discussed by chemical analysis and infrared spectroscopy.
