摘要
采用活性炭纤维处理含氟模拟废水,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,并研究了吸附平衡时间、pH、活性炭纤维用量、氟离子初始浓度对处理效果的影响。结果表明,活性炭纤维对氟的吸附速率快,对低浓度含氟废水的处理效果也相当好,溶液pH、吸附时间均存在最佳值。吸附饱和的活性炭纤维用0.01%～0.05%的氢氧化钠溶液再生,重复实验,吸附效率无明显变化。
Activated carbon fiber（ACF） is used to treat fluoride-containing waste-water.Adsorption isotherm and dynamic adsorption breakthrough curve are determined.The effects of factors such as pH,amount of ACF,the prime concentration of and adsorption time on adsorption efficiency have been studied.It has been found that maximum adsorption of fluoride from waste-water takes place at pH value of 6.5 and 60 minutes of adsorption time.ACF regenerated by NaOH of 0.01-0.05% conc.has not much difference in adsorption efficiency after cycles.Adsorption rate of ACF for fluoride is fast and regeneration is simple.
