摘要
研究了高岭土类、蒙脱石类、海泡石和沸石类矿物经强酸、强碱和80℃处理后的阳离子交换吸附容量。结果表明:pH值和80℃处理温度对粘土矿物的阳离子交换容量均有影响,粘土矿物的阳离子交换容量主要受其晶体结构的影响;沸石类、高岭土类及海泡石粘土矿物的耐酸、碱及热稳定性良好;蒙脱石类粘土矿物耐酸、碱及热稳定性较差。
Abstract： The research concerns in the determination of the cation exchange capacity （CEC） of kaoline, montmorillonite, sepiolite and zeolite mineral treated by acid solution, alkali solution and heating at 80℃, respectively. The results indicate that the pH value and temperature of 80℃ all have influence on the CEC of clay mineral. And the CEC of the samples is mainly affected by their crystal structure. Acid, alkali and heating treatment corrosion resistances of zeolite, kaoline and sepiolite are better, while the montmorillonite＇s are worse.
