| 摘 要： | 用氧化铁凝胶在溶液中进行对稀土离子的吸附实验，得到的数据符合Ｆｌｏｒｙ－Ｈｕｇｇｉｎｓ等温式，计算了标准摩尔吸附吉布斯函数、标准摩尔吸附熵和标准摩尔吸附焓。零电荷点和等电点的测量结果表明发生了特性吸附。氧化铁凝胶骨架上的ＯＨ基团是产生特性吸附的内在原因

| Abstract: | Experiments of absorption of rare earth ions have been carried out in solution with iron oxide gel.The data gained from it are in accordance with the result from Flory Huggins isothermal formula.The standard Gibbs functions of molar absorption,standard molar absorption entropy and standard molar absorption enthaply are calculated in the paper.The measurement of the zero charge points and isoelectric points shows occurance of the characteristic absorption.The fact proves that the OH radical on the skeleton of iron oxide gel is the innate cause of the characteristic absorption. |
