摘　　要：以乙烯砜作交联剂,聚乙烯醇作包膜材料,对P204浸渍树脂进行稳定化处理,得到稳定化的P204浸渍树脂。研究了该树脂在硫酸介质中吸附铟的性能。静态实验表明,稳定后的P204浸渍树脂对铟具有较好的吸附性能。经过8次吸附-洗脱-吸附循环后,该树脂的吸附容量变化很小。其最佳吸附pH为2.5,最大吸附容量为16.7 mg.g-1。升温不利于吸附。其等温吸附式符合Langmuir式。Solvent impregnated resins（SIRs） that were stabilized by coating with vinyl sulphone crosslinked poly（vinyl alcohol） were employed for uhe adsorption of indium ions from sulfate solution.Batch sorption studies were showed that the SIRs containing P204 were effective for the adsorption of indium ions from aqueous solution.The sorption performance of SIRs remained almost constant after eight sorption-elution-sorption cycles.The optimum pH was 2.5.The saturation adsorption capacity was 16.7 mg·g-1 of SIRs.The adsorption was favored by decreasing temperature.The isothermal adsorption accorded Langmuir isotherm model.
