| 摘 要： | 采用溶液浸溃一加热法制备栽铁颗粒活性炭(10CGAC).并通过SEM/EDAX进行表征,研究了不同实验条件(pH值、初始浓度、吸附剂投加量和共存无机离子)下吸附除Cr(Ⅵ)的效果.结果表明:随着pH值的升高,吸附去除率降低;相同实验条件下,10CCAC的吸附效果明显优于颗粒活性炭(GAC);SO12-对吸附具有抑制作用.吸附动力学实验数据符合准二级反应动力学模型,温度升高,反应速度常数以及吸附容量也随之增加.

| Abstract: | Iron oxide coated granular activated carbon (IOCGAC)was synthesized by solution immersion-heating technique and characterized by SEM/EDAX. The adsorption experiments were performed under different conditions in terms of pH, initial concentration of Cr(VI), adsorbent dosage and coexistence inorganic ions. The results indicated that the removal efficiency of Cr(VI)reduced with the increase of pH. The adsorption efficiency of IOCGAC was much higher than that of GAC under the same condition. The existence of SO... |
