A large amount of iodine-containing solution (ICS) is produced in both nuclear medicine and the atomic energy industry, which may cause serious health hazards in case if it enters aquatic ecosystem without sufficient treatment. The treatment of ICS by silver demonstrates great potential for iodine capture and retention. Nano-scale silver and its oxide particles formed on the surface of Al₂O₃ via electroless plating was introduced to ICS treatment. A series of batch sorption experiments against ICS by Ag-Ag₂O modified Al₂O₃ (Ag-Ag₂O-Al₂O₃) has been conducted. Ag-Ag₂O-Al₂O₃ was characterized by SEM, FTIR, XRD, and XPS before and after the reaction. The results show that ~ 82.6% of I⁻ was removed by 4.0 g/L Ag-Ag₂O-Al₂O₃ from the solution containing 0.3 mg/L I⁻ at pH 3 and at 298 K. Ag-Ag₂O-Al₂O₃ was effective in low concentration artificial nuclear medical ICS treatment. Thermodynamic analysis showed that the reaction consistent with the Langmuir model and was a uniform exothermic reaction of a single layer. Therefore, Ag-Ag₂O-Al₂O₃ prepared by electroless plating could be considered as a potential material for the ICS treatment.

核医学和原子能工业都会产生大量含碘溶液（ICS），如果未经充分处理进入水生生态系统，可能对健康造成严重危害。用银处理 ICS 显示了碘捕获和保留的巨大潜力。通过化学镀在Al ₂ O ₃表面形成的纳米级银及其氧化物颗粒被引入ICS处理。已经通过Ag-Ag ₂ O 改性的Al ₂ O ₃ (Ag-Ag ₂ O-Al ₂ O ₃ )对ICS进行了一系列批量吸附实验。Ag-Ag ₂ O-Al ₂ O₃反应前后用SEM、FTIR、XRD和XPS表征。结果表明，约 82.6% 的 I ^-在 pH 3 和 298 K 下被 4.0 g/L Ag-Ag ₂ O-Al ₂ O ₃从含有 0.3 mg/LI ^-的溶液中去除。Ag-Ag ₂ O- Al ₂ O ₃对低浓度人工核医学ICS治疗有效。热力学分析表明，该反应符合朗缪尔模型，为单层均匀放热反应。因此，Ag-Ag ₂ O-Al ₂ O ₃ 通过化学镀制备的可被认为是 ICS 处理的潜在材料。
