放射性碘在環(huán)境中的高毒性和高遷移性會對人體健康造成嚴重危害。碘酸鹽是環(huán)境中碘的主要種類之一,是工業(yè)消毒的重要副產(chǎn)品。還建議作為鹽的添加劑來糾正碘缺乏。從公共衛(wèi)生和環(huán)境保護的角度來看,從水溶液中去除IO₃^-具有重要意義。鋁是一種流行的吸附材料。金屬涂層對某些特定污染物的吸附能力有所提高。在大顆粒上鍍銅。Cu-Al₂O₃、Fe-Al₂O₃和Cu-Al₂O₃對I0₃^-的吸附需要70小時才能達到吸附平衡,K_d分別為102、92和38 ml/g。吸附動力學遵循偽二階模型。K_d降低,而IO₃^-的初始濃度從5增加到120 ppm。等溫線用弗倫德利希模型很好地描述了。當溫度升高時,K_d降低,吸附過程為非自發(fā)吸熱反應。在酸性條件下,IO3的吸附性能得到改善。本研究中的最大K
