| 摘 要： | 利用芭蕉芋渣填料柱对水中亚甲基蓝(MB)进行动态吸附.探讨了初始质量浓度、床层高度、pH值等因素对穿透曲线的影响,运用数学模型对在不同层高和质量浓度下的吸附数据进行拟合.结果表明,芭蕉芋渣能有效去除水中的亚甲基蓝,随着床层高度的增高、pH的增大和初始质量浓度的减小,芭蕉芋渣填料柱对水中亚甲基蓝的吸附穿透曲线位点向右移....

| Abstract: | The capability of canna edulis kerl residual to adsorb methylene blue(MB)from aqueous solution was investigated in a fixed-bed column.The effects of important parameters on breakthrough curve,such as the filler height,pH and concentrations of MB were studied.Mathematical dynamic model respectively at different filler height,different pH and different concentrations of high-layer adsorption data were applied to simulate column adsorption data and to obtain relevant parameters.The results showed that canna ed... |
