Abstract

The objectives of this research were to synthesize MANGANESE DIOXIDE NANOPARTICLES and determine their efficiency in the REMOVAL OF LEAD from AQUEOUS SOLUTIONS. Consequently, MANGANESE DIOXIDE NANOPARTICLES were synthesized by the cathode electrochemical deposition method and the effect of pH, contact time, lead concentration and quantity of nanoparticles on lead removal efficiency were investigated through the batch system. A scanning Electron Microscope (SEM), XRD and FTIR were used to characterize the synthesized MANGANESE DIOXIDE NANOPARTICLES. SEM results showed that the diameter of the particles is 30-50 nm and the results also showed that the optimum pH value for adsorption was 6. The adsorption capacity increased and the adsorption efficiency decreased with increasing concentration of lead ions and by reducing the amount of adsorbent. In a study of the adsorption isotherm, experimental data from the Langmuir model to follow. The data obtained in this study showed that the absorption of lead absorption kinetics model obeys the model of Hu and colleagues. The overall results of this study showed that the use of MANGANESE DIOXIDE NANOPARTICLES was a suitable method with high potential for the REMOVAL OF LEAD from AQUEOUS SOLUTIONS.
