Fe/MnO2 was prepared from hydrothermal procedure, and its properties for removal of arsenic from aqueous solution were investigated. The samples were characterized with XRD, SEM and FTIR. SEM images revealed the Fe/MnO2 was dispersing flower-like sphere with the diameter of 500-800 nm and the width of petal was of 20-30 nm. Sorption of the arsenic to Fe/MnO2 reached equilibrium in less than 180 s, which was the much faster than that of pure MnO2 and amorphous iron manganese binary oxide. The adsorption isotherm was agreed well to the Freundlich adsorption model with maximum adsorption capaciti...
