摘要
对云南文山膨润土的理化性能进行系统研究,确定了化学组成,并进行钠化改性实验。通过XRD、DTA及IR等对晶相结构进行分析表明,该膨润土为钙基膨润土,吸附性能较好,经钠化改性后其性能可达到一级土标准,有较好的应用前景。
The physicochemical properties of the bentonite from Wenshan were studied and its chemical composition was determined ,The bentonite was Na-modified. In addition the crystal structures of the bentonites were characterized and analyzed by XRD, DTA and IR techniques. The results indicate that the bentonite from Wenshan is Ca-bentonite, which has good adsorption. After Na-modification the properties of the bentonite can reach to the first level and its application has broad prospects.
