| 摘 要： | 以活性炭为载体,制备了负载型纳米铁除砷吸附剂.以除砷效率为目标,优化了制备过程中活性炭的不同粒径、铁盐种类及浓度、反应温度及速度、铁盐浸泡活性炭时间及反应平衡时间等参数.考虑到除砷效率及工程实际的应用,室温时采取活性炭粒径为20～40目、KBH4的滴加速率为lml·min-1、活性炭经铁盐为质量浓度为6.9％的硫酸亚铁浸泡30 min,反应平衡时间为30 min时所制备的吸附剂综合除砷效果最好(98％).

| Abstract: | Taking activated carbon as a carrier,an activated carbon-loaded nano zero-valent iron(NZVI/AC) adsorbent was prepared for arsenate(As(V) ) removal.With the removal rate of As(V) as the target,an optimization was conducted on the particle size of activated carbon,the species and concentrations of iron salts,the reaction temperature and reaction rate,the marinated duration of iron salts in activated carbon,and the equilibrium time of reaction.In considering of the As(V) removal rate and the practical utilizat... |
