The Manganese oxide/active carbon fiber (MO/ ACF) was prepared and its electrosorptive properties of Cd(II) in aqueous solution were investigated. The structure of MO/ACF was characterized with transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. Furthermore, the Cd(II) electrosorptive properties of MO/ACF electrodes with different bias potentials, ionic strengths, and loaded amount of manganese oxides were measured and the electrosorption isotherm and kinetics were investigated. The Cd(II) electroso...
