| 摘 要： | 该文就Fe(0)同步氧化吸附去除原水中的As(Ⅲ)的影响因素进行了研究。研究结果表明,当原水中的As(Ⅲ)的浓度为100μg/L时,在Fe(0)与As(Ⅲ)的质量比为1 000∶1,pH=5.0时,经过240 min接触时间,As(Ⅲ)的去除率达到90%以上,且As(Ⅲ)的去除率随溶解氧浓度的增加而增加。 |
| 关 键 词： | 零价铁[Fe(0)] 三价砷[As(Ⅲ)] 吸附 |

| Abstract: | Factors of that As(Ⅲ) can be synchronously oxidized and absorbed by Fe(0) in raw water were studied.The results showed that when the raw water As(Ⅲ) concentration of 100 μg/L,the As(Ⅲ) removing efficiency was over 90 % after 240 min of mixing while the mass ratio of Fe(0) to As(Ⅲ) was 1 000 ∶ 1,pH=5.0.As(Ⅲ) removing efficiency was improved with the increasing of dissolved oxygen concentration. |
| Keywords: | zero-valent iron[Fe(0)] tri-valent arsenic[As(Ⅲ)] adsorption |
