Hydrothermally synthesized MnO2 nanowires and their application in Lead(II) and Copper(II) batch adsorption
Original language description
Manganese oxide (Mn2O) nanowires with diameters of 20nm to 100nm are synthesized by hydrothermal method. Chemical characterization of these nanostructures demonstrates the formation of Mn(IV), corroborating the MnO2 compounbd. The nanowires were used as adsorbents of Pb(II) and Cu(II) ions from water in batch system at room temperature. The results indicate faster adsorptin rates and better affinity towards Pb(II) compared to Cu(II), since the adsorption capacity an percentaje of removal at equilibrium for Pb(II) are higher than those for Cu(II). The kineticsof adsorption was described by a pseudo-second order rate model for both ions, and Wbeber and Morris intra-particle diffusion model was used to a better understanding of the preocess. In addition, the Langmuir and Freundlich models were used to describe the isotherms, the first model was better adjusted for Cu(II) adsorption and the later for Pb(II) adsortpion.
