文章探讨了直接红染料在粉煤灰上的吸附行为及其机理。结果显示,粉煤灰对直接红染料有较好的去除效果;当NaCl浓度≤12.5 g/L,盐分增加对直接大红的去除率影响不明显,NaCl浓度≥15 g/L,盐分增加,直接大红的去除率有所增大;当十二烷基磺酸钠浓度≤0.5 g/L,直接大红在粉煤灰上的吸附量随表面活性剂浓度上升明显下降,继续增加表面活性剂浓度,影响则不明显。

This paper studies the behaviors and mechanisms of direct red dye adsorption on fly ash.The results show that fly ash achieved better direct red dye removal performance.When NaCl concentration was below 12.5 g/L,the increase of salinity had small influence on removal rate.The direct red removal rate increased with the increase of salinity when NaCl concentration was above 15 g/L.However,when concentration of sodium dodecyl sulfate was below 0.5 g/L,the adsorption of direct red dye on fly ash decreased with the increase of surfactant concentration.No significant effects were observed when continue to add surfactants.
