| 摘 要： | 以XRD、FTIR、TEM和热失重等分析手段对广丰膨润土进行了表征,物相分析表明广丰膨润土为钙基膨润土,主要矿物成分有蒙脱石、石英、白云母等.对广丰膨润土进行了提纯,蒙脱石含量可达89%.以碳酸钠作改性荆对提纯土进行钠化改性,改性后钠基土的CEC为114mmol/100g,XRD显示d_(001)=1.235nm,钠化改性效果较好.

| Abstract: | The bentonite from Guangfeng was characterized and analyzed by XRD, FTIR, TEM and TG-DSC techniques. The results indicated that the bentonite from Guangfeng was Ca-bentonite, which was mainly composed of montmorillonite, quartz and muscovite. The bentonite was purified and its montmorillonite cntent could reach to 89%. The Na-bentonite was prepared from Ca-bentonite with sodium carbonate as modified agent after purification with water. That results showed that the d001 of the modified Na-bentonite is 1.235n... |
