【摘要】：合成了鐵鋁復(fù)合材料吸附劑,并比較了其與酸改活性炭、陶粒、類水滑石3種吸附材料對(duì)含砷廢水中As(Ⅲ)的去除效果。結(jié)果表明,鐵鋁復(fù)合材料對(duì)水中三價(jià)砷的吸附效果好于其它3種吸附材料,吸附率大于89%。鐵鋁復(fù)合材料對(duì)水中As(Ⅲ)的吸附符合Langmuir等溫模型和Freundlich等溫模型,吸附作用力既涉及離子交換和靜電吸引,又涉及表面配位作用。
[Abstract]:The effect of 3 adsorbents on As (III) in arsenic containing wastewater was compared with acid modified activated carbon, ceramsite and hydrotalcite. The results showed that the adsorption of trivalent arsenic in water was better than that of other 3 kinds of adsorbents, and the adsorption rate was greater than the absorption of As (III) in water with 89%. iron and aluminum composites. With the Langmuir isothermal model and Freundlich isothermal model, the adsorption force involves ion exchange and electrostatic attraction as well as surface coordination.
