摘要
系统考察了我国不同产地膨润土的可交换阳离子组成、p H值以及碱性系数 ,根据层间阳离子组成对各地膨润土进行了属性分析。研究表明 ,所选矿区膨润土大多是钙基土 ,矿样的层间阳离子组成存在差异。讨论了膨润土层间阳离子种类、p H值、碱性系数以及其属性之间的关系。对比不同属性划分法后发现 。
The composition, pH value and alkaline coefficient of exchangeable cation from various bentonites in China were investigated. The property of bentonites was analysed based on composition of the interlayer cation. Research shows that the interlayer cations of bentonite were mainly composed of Ca 2+ and difference exists among different samples and deposits. The authors believe that the ion-ratio method is an efficient one for classification of bentonite reflecting type and amount of interlayer cation.
