| 摘 要： | 对于某一特定的膨润土矿,蒙脱石含量与阳离子交换容量呈正相关,以此为依据提出了一种确定蒙脱石含量的新方法——纯样品指标标定法。对山东莱西、潍坊两地膨润土矿的实际测定结果显示,利用纯样品指标标定法确定蒙脱石含量取得了较满意的结果,说明此方法具有较大的使用价值。该方法考虑了膨润土中杂质、蒙脱石层间可交换阳离子类型及端面电荷对测定结果的影响,推荐以钠基土为试样,在pH=4的条件下采用加权法测定蒙脱石含量。

| Abstract: | A new method called pure sample standardization was established based on the theory that motomorillonite contents have a positive correlation with cation exchange capability to a specific bentonite ore.Actually measured results of bentonite from Laixi and Weifang indicated that motomorillonite contents calculated by pure sample standardization were accepted,which illustrated that pure sample standardization had a rather large use-value.Influence of impurity,cation exchange capability type and edge charge on... |
