Comparison of Pb2+ Removal Efficiency by Zero Valent Iron Nanoparticles and Ni/Fe Bimetallic Nanoparticles abstract
In this study, synthesized bimetallic Ni/Fe nanoparticles and zero-valent iron nanoparticles (nZVI) were investigated for remediation of Pb2+ against the effect of various parameters such as pH, volume to mass(V/m) ratio, contact time, initial concentration of Pb2+ on removal efficiency. Results of the present projectsuggest both Ni/Fe bimetallic nanoparticles and nZVI adsorbents have shown maximum removal of Pb2+ at pH5 with an increasing trend with increasing pH. The V/m ratio optimization study reveals that the same volume of the lead solution requires more Ni/Fe bimetallic nanoparticles than nZVI. The time to achieve equilibrium is same in both the cases. Similarly, decrease in the removal efficiency with increase in initial concentration of Pb2+ is observed in both the cases
