摘要
采用活性炭纤维 (ACF)对含镉模拟废水进行了静态和动态吸附研究 ,测定了静态吸附等温线和动态穿透曲线 ,并研究了PH值、吸附平衡时间对处理效果的影响 ,采用浓度为 0 0 3mol/L的HCL溶液作解吸液回收Cd2 + 的综合效果较好 ,静态法的吸附率和解吸率分别略高于动态法的吸附率和解吸率 ,但动态法耗时短 。
Activivated carbon fiber(ACF) is used to study on static and dynamic adsorption of the Cadium wastewater.Adsorption isotherm and dynamic adsorption breakthrough curve are determined.The effects of factors such as pH and adsorption time on adsorption efficiency have been studied.Using 0.03mol/L of HCL solution for recovering cadium has satisfactory effect.Althogh the adsorption and desorption efficiencies of static method are slightly higher than that of dynamic method,the latter needs less time and is more suitable for industrial application
