摘要
用室温电解法制得的二氧化锰在弱酸性溶液中对稀土离子进行吸附实验，得到的数据符合Ｆｒｕｍｋｉｎ等温式。求出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。ｐ．ｚ．ｃ．和ｉ．ｅ．ｐ．的测量结果表明发生了特性吸附。
The adsorption experiment of rare earth ions on MnO 2 obtained by room temperature electrolysis in weak acid solution was carried out with final data consistent with Frumkin isotherm.Standard molar adsorption Gibbs function,standard molar adsorption entropy and standard molar adsorption enthalpy are derived.The measurement of p.z.c and i.e.p demonstrates that the characteristic adsorption happens,which is caused by the linkage of OH genes on MnO 2 molecular skeleton.
