合成了铁铝复合材料吸附剂,并比较了其与酸改活性炭、陶粒、类水滑石3种吸附材料对含砷废水中AS(Ⅲ)的去除效果。结果表明,铁铝复合材料对水中三价砷的吸附效果好于其它3种吸附材料,吸附率大于89%。铁铝复合材料对水中As(Ⅲ)的吸附符合Langmuir等温模型和Freundlich等温模型,吸附作用力既涉及离子交换和静电吸引,又涉及表面配位作用。

A kind of Fe-Al bimetallic adsorbent was prepared and compared with other three kinds of adsorbent, including the acid-modified activated-carbon,ceramsite and hydrotalcite-like compound, for investigating their effects on removal of As(Ⅲ) from As-containing wastewater. Results showed that Fe-Al bimetallic material had a better effect of As(Ⅲ) adsorption than other 3 adsorbents, with an adsorption efficiency over 89%. It is found the As(Ⅲ) adsorption by Fe-Al bimetallic material conforms to Langmuir isotherm model and Freundlich isotherm mode...
