摘要:
以红薯叶提取物为原料绿色合成 Fe/Cu纳米复合材料,用其处理含有罗丹明B(RhB)的废水，并采用响应面法(RSM)对吸附时间、吸附剂用量、pH等吸附条件进行了优化。吸附平衡数据符合Sips等温模型,且热力学参数表明对罗丹明B的吸附过程是一个自发的吸热过程。准二级动力学模型能很好地描述Fe/Cu纳米复合材料对罗丹明B的吸附过程。在298K时,Fe/Cu纳米复合材料对罗丹明B的最大吸附量是484.18mg/g,表明Fe/Cu纳米复合材料在罗丹明B废水处理上有较好的应用前景。
Abstract:
Fe/Cu nanocomposites prepared from sweet potato leaves were investigated for the removal of Rhodamine B(RhB) from aqueous solution. The effects of various parameters such as adsorption time, adsorbent dosage and pH were optimized by response surface methodology (RSM). The adsorption equilibrium data were well fitted with Sips model, and the thermodynamic study indicated that the adsorption process was a spontaneous endothermic process. The pseudo-second order kinetics model could describe well the adsorption process of RhB onto Fe/Cu nanocomposites. At 298 K, the maximum adsorption capacity of Fe/Cu nanocomposites for RhB was 484.18 mg/g, indicating that Fe/Cu nanocomposites had a good application in RhB waste water treatment.
