| 摘 要： | 考察了六种典型的膨润土原矿对亚甲基蓝溶液的脱色处理效果.结果表明,使用各矿样12min后染料试液均达到了85%以上的脱色率,其中和丰、淳化、临安以及甲山膨润土原矿脱色效果高达97%以上.由于各膨润土矿地质背景不同,因而各膨润土呈现物理化学性质的矿样间差异性较大.结合膨润土样品的物理化学性质和染料脱色效果,得出结论,影响膨润土样品吸附的因素主要有膨润土d001值﹑CEC﹑内表面积以及pH值;而膨润土的水理特性对样品吸附的速率影响较大.

| Abstract: | The decolorizing performances of six bentonite samples were investigated in the methylene blue aqueous solution. The results showed that the decolorization rate of methylene blue on bentonetes are all over 85%, and those of the crude bentonete samples from Hefeng, Chunhua, Lin'an and Jiashan are all beyond 97%. The differences in their physicochemical properties existed among different bentonite samples owing to different mineral-producing environments. Relating the decolorizing performances of bentonite with their physicochemical properties, it can be found that the d001 value, CEC, pH value and inner surface area of the bentonite are the main factors influencing the adsorptive decolorization of dye on the crude bentonite. And the hydrophysical propertie of bentonite was the main factor influencing the adsorptive speed. |
