摘 要: 研究不同pH值和温度下草酸铈在云母表面吸附量的变化，分析pH值和温度对云母吸附草酸铈的影响。结果表明：pH值在6.5～7.5，温度在65～75 ℃时有利于草酸铈在云母表面的吸附；草酸铈在云母表面的吸附主要是云母表面对草酸铈的静电作用以及草酸铈自身的团聚作用的结果。

Abstract:The adsorption capacity of Ce2(C2O4)3 on the muscovite surface was estimated under different pH values and temperatures. The effects of pH value and temperature were analyzed in the course of adsorption. The results show that the pH value of 6.5−7.5 and the temperature of 65−75 ℃ will promote the adsorption of Ce2(C2O4)3 on the muscovite surface. The further analysis indicates that the electrostatic sorption and self-reunion of Ce2(C2O4)3 are the primary causation for the adsorption of Ce2(C2O4)3 on the muscovite surface.
