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) electrosorptive capacity of MO/ACF was 6 times higher than that of pure ACF. The optimal adsorptive bias voltage was 1.5 V and the optimal electrolyte concentration of NaCl was 0.1 mol/L. The adsorption isotherm was agreed well with the Freundlich adsorption model and its maximum electrosorption capacity was 14.88 mg/g by Langmuir model. The higher adsorptive capacity of MO/ACF than that of pure ACF is attributed to higher capacitance and more adsorptive sites of MO/ACF.
