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。二氧化锰分子骨架上有ＯＨ基团连接是产生特性吸附的原因
The room temperature electrolytic manganese dioxide obtained in weak acid solution of rare earth ions adsorption experiments, the data obtained in line with Frumkin isotherm. The standard molar adsorption Gibbs function, the standard molar adsorption entropy and the standard molar adsorption enthalpy were obtained. p. z. c. And i. e. p. The measurement results show that the characteristic adsorption occurs. Manganese dioxide molecular framework OH groups connected to produce the characteristics of adsorption
