摘 要: 研究不同pH值和溫度下草酸鈰在云母表面吸附量的變化，分析pH值和溫度對云母吸附草酸鈰的影響。結(jié)果表明：pH值在6.5～7.5，溫度在65～75 ℃時(shí)有利于草酸鈰在云母表面的吸附；草酸鈰在云母表面的吸附主要是云母表面對草酸鈰的靜電作用以及草酸鈰自身的團(tuán)聚作用的結(jié)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.
