摘要
利用膨润土层间域的活性 ,采用无机物插入 ,对其进行改性 ,并研究各种改性膨润土对红色染料的脱色性能 .结果表明 ,改性膨润土的脱色性能比原土有较大的增强 .以一种脱色性能较好的改性膨润土为代表 ,探讨脱色的适宜条件和脱色机理 .
Based on the activity of interlamellar domain of bentonite, bentonite was modified by adopting the insertion of inorganic matter; and the decoloring performance of various modified bentonite on orcein dye was studied. The results indicated that the decoloring performance of modified bentonite was greatly increased as compared with that of unmodified one. Exemplifying by one kind of bentonite with fairly good decoloring performance, the authors inquired into appropriate conditions of decoloration and investigated the mechanism of decoloration.
