利用大蒜渣负载型纳米零价铁对脱除水中Cu2+的反应行为和效果进行了探索,并对其脱除机理做了探讨。试验发现,在初始Cu2+浓度20mg/L、pH=4,固液比为25mg/15mL的条件下,用负载纳米零价铁的大蒜皮对废水进行吸附,废水中Cu2+的去除效率最高可达94.15%。
Abstract：Reaction behavior and effect of garlic residual particles loaded nano zero valent iron on removal of Cu2+ from waste water were explored.The removal mechanism was discussed.The results show that removal rate of Cu2+ from waste water is up to 94.15% under the conditions including initial Cu2+ concentration of 0.002%,pH value of 4,and ratio of solid to liquid of 25 mg/15 mL.
