| 摘 要： | 采用活性碳纤维处理苯酚模拟废水，通过静态和动态吸附研究，测定了吸附等温线动态穿透曲线，并研究了溶液的pH值、吸附平衡时间对处理效果的影响。结果表明，活性碳纤维对苯酚的吸 附容量为275.1mg/g，吸附速率快，当溶液pH＞8时，吸附效率下降，吸附时间存在最佳值。吸附饱和的活性碳纤维用10％的氢氧化钠溶液再生，重复使用3次，吸附效率无明显变化。

| Abstract: | Taking model treatment of phenolic sewage by activated carbon fibre by static and dynamic adsorption study, the penetratingcurve of iso-thermal dynamic state adsorption line is determined and the influence of treatment effect by pH and adsorption equilibrium time are studied. Result indicates that the adsorption capacity of activated carbon fibre to phenol is 275.1mg/g, while the fast adsorption rate and solution with pH greater than 8, the adsorption efficiency decreases; and there is a best value for adsorption time. The saturated carbon fibre by adsorption is recovered by employing 10% sodium hydroxide solution, and there will be no significant change of adsorption efficiency after reuse for three times. |
