Nanoscale Zero Valent Iron Supported on Montmorillonite Clay for the Removal of Cu(II) from Aqueous Solution
In this study, a simple procedure for the formation of composite with nanoscale zero valent iron (nZVI) and montmorilonite (MMT) clay is reported in this study. The prepared composite was characterized with SEM, EDAX, FTIR and XRD. The degradation efficiency of the prepared composite for Cu(II) ion from aqueous solution has been found to be dependent on contact time, initial concentration, pH and dosage of adsorbent and it was found to be 96%. Removal of Cu(II) ion followed pseudo second order kinetics. The analysis of adsorption under different initial concentrations followed Freundlich model. The thermodynamic study revealed that the adsorption process was endothermic. Probable mechanism of adsorption and a comparative study of the present material with other materials reported previously were also included. The prepared nZVI with MMT was found to be an excellent composite for the adsorption of Cu(II) ion from aqueous solution.
