| Abstract Scope |
This research work analyzed the use of Manganese dioxide nanoparticles for the removal of manganese present in aqueous effluents. In this Research Project, nanoparticles of MnO2-α present in the industrial anode residue from the zinc electrolysis process were used as nanoadsorbent to remove manganese ions present in industrial aqueous effluents and in a synthetic effluent. The MnO2-α nanoparticles were characterized by X-ray Diffraction, XRD and by Scanning Electron Microscopy, SEM, the results of which showed that the crystallite sizes were in the order of 15nm and that they had a rod-shaped morphology. According to the results obtained, it was determined that the highest efficiency to remove manganese ions from industrial aqueous effluents was achieved using 0.08 g of MnO2-α of anodic residue in 20mL of aqueous effluent, pH = 6.45, time of 60 min and a stirring speed of 800RPM, reaching a manganese removal of 86.88%. |
