摘要
本文研究了凹凸棒石粘土处理阳离子染料废水的吸附脱色规律,结果表明,粉末凹凸棒石对水溶性阳离子染料具有优良的脱色效果。例如,染料初始浓度100mg·l^(-1)（色度相当于2200—4000倍）,粘土投加量0.5％,七种被研究的阳离子染料废水平均脱色率近99％,吸附机理主要是离子交换。
The adsorption of attapulgite clay on soluble cationic dyes was studied . The results showed that the clay has an excellent performance in colour removal of soluble cationic dyes. Such as,simulated wastewater containing dye 100mg·l-1 was treatment by the day dosaging 0. 5%. After solid-liquid separation,the colour removal average of seven types of dye investigated was nearly 99%. The adsorption mechanism belongs ionic ex-change.
