摘要
本研究成功制备了一种Fe-Mn-Zr复合磁性吸附材料,并研究了其对As(V)的吸附性能。结果表明,大部分砷吸附在最初的6 h完成,30 h内可以达到吸附平衡。吸附最佳pH值为3.0,吸附等温线符合Langmuir吸附等温模型。在初始pH值5.0时,最大吸附量为81.3 mg/g。
behavior for As(V) was investigated. The kinetics study showed that most of the uptake took place in the first 6 h, and the adsorption equilibrium was obtained within 30 h. The optimal pH for As(V) adsorption was around 3.0. The Langmuir equation well described the adsorption isotherm, and the maximum adsorption capacity was 83.1 mgAs/g when the initial pH was 5.0.
