摘要：
Fe-Mn binary oxide flower-like three-dimensional nanostructure synthesized from a hydrothermal procedure was used to remove arsenic (As) from aqueous solution. The samples were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier-transform infrared spectrometry (FTIR). SEM images revealed that the Fe-Mn binary oxide was dispersed as flower-like spheres with a diameter of 500 - 800 nm and the width of the petals was 20 - 30 nm. Sorption of the As to the Fe-Mn binary oxide reached equilibrium in less than 180 s, which is much faster than pure MnO2 and amorph...
