英文摘要	The commercial Fe-Si-B metallic glass (Fe-Si-BMG) powder and the widely used powder of zero valent iron (ZVI), namely Fe0, were used to eliminate the Ni(II) from aqueous solution. Kinetic analysis results indicate that the removal efficiency of Fe-Si-BMG powder in removing Ni(II) is about 38 times faster than that of the Fe0 powder. Morphology observation shows that the product layers on the surface of Fe-Si-BMG powder are composed of homogeneous and loose whiskers, which peel off more easily from the surface during the agitation process, compared with those of Fe0 powder. Chemical composition analysis about the surface of Fe-Si-BMG powders before and after reaction shows that Fe-Si-BMG powder can eliminate the Ni(II) through surface adsorption, reduction, and coprecipitation mechanisms; while Fe0 powder removes the Ni(II) in solution mainly through surface adsorption and coprecipitation mechanisms.
