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 pHwere optimized by response surface methodology (RSM). The adsorption equilibrium data were well fitted with Sipsmodel, 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 nanocompos-ites. At 298 K, the maximum adsorption capacity of Fe/ Cu nanocomposites for RhB was 484.18 mg/g, indicatingthat Fe/Cu nanocomposites had a good application in RhB waste water treatment.
