摘　　要：研究了不同活化条件下活化蒙脱石脱色力与层间和八面体金属阳离子的溶出率关系,讨论了活化产品b轴有序度的变化,蒙脱石八面体金属阳离子的适量溶出对脱色力的影响至关重要,通过硅铝比、脱色力对八面体阳离子总溶出率的回归分析、b轴有序度降低率,可预测脱色性能。Under different processing conditions, the relationship between decolouring capacity of activated montmorillonite and dissolving ratio of metallic cation in the layer and the octabedron area of the montmorillonite was studied, and the variety of b-axls order of the activated montmorillonite was discussed. It was found that the metallic cation in the octahedron area of the montmorillonite plays an important part to decolouring capacity of the activated montmorillonite. And the decolouring capacity of activated montmorillonite can be forecasted by study of the ratio of silicon to aluminitun, the regress analysis between the total dissolving ratio of metallic cation in the octahedron area of montmorillonite and study on the falling ratio of b-axis order.
