Synthesis of and Characterization of Polyhedron of Mn₂O₃ Nanoparticles Using Spent Zn-Mn Batteries

Abstract:

Polyhedron composed of Mn₂O₃ nanoparticles with an average diameter of 0.5-1.0 μm have been prepared using spent Zn-Mn batteries. The product was characterized by X-ray powder diffraction and scanning electron microscope. The adsorption performance of polyhedron composed of Mn₂O₃ for 2-(5-Bromo-2-pyridylazo)-5-(diethylamino) phenol was investigated. The adsorbent showed high efficiency for the removal of 2-(5-Bromo-2-pyridylazo)-5-(diethylamino) phenol in water. The equilibrium of adsorption was achieved within 40 min. The isotherm adsorption data obeyed the Langmuir model, with a maximum adsorption capacity of 62 mg g^-1.
