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.
