| 摘 要： | 以小麦秸秆、木屑、煤渣等所制备的活性炭及其活性炭负载铁作为吸附剂,用于水中As（Ⅲ）的去除。考察了活性炭种类、吸附时间、吸附温度、溶液pH值和吸附剂投加量等对As（Ⅲ）去除的影响。结果表明,木屑制备的活性炭所负载铁作为吸附剂,对水中As（Ⅲ）的去除效果最好;As（Ⅲ）的去除率随吸附时间、吸附温度、溶液pH值和吸附剂投加量的增加而增加。

| Abstract: | Wheat straw,sawdust,coal,etc. prepared and activated carbons as an adsorbent load of iron,for the removal rates of As（Ⅲ） in water. The effects of carbon type,sorption time,temperature,pH value and the adsorbent dosage on As（Ⅲ） removal were investigated. The result showed that iron load activated carbon prepared by wood as adsorbent illustrated the best removal rate for As（Ⅲ） in water. The removal rate for As（Ⅲ） increased with the increasing sorption time,temperature,pH value and the adsorbent dosage. |
