MG）粉末和目前廣泛應(yīng)用的零價(jià)鐵粉（ZVI，F(xiàn)e0）對(duì)水溶液中重金屬離子Ni(II)的去除性能。動(dòng)力學(xué)分析顯示Fe-Si-BMG粉末對(duì)Ni(II)的去除效率約為Fe0粉的38倍。通過(guò)對(duì)2種粉末的表面形貌觀察發(fā)現(xiàn)，與Fe0粉相比， Fe-Si-BMG粉末的表面產(chǎn)物層具有均勻、疏松的絮狀物，更容易在攪拌過(guò)程中脫落。通過(guò)對(duì)Fe-Si-BMG粉末反應(yīng)前后的表面化學(xué)成分分析發(fā)現(xiàn)：Fe-Si-BMG粉末通過(guò)吸附、還原、共沉淀作用去除水溶液中Ni(II)，而Fe0粉主要通過(guò)吸附和共沉淀去除水溶液中的Ni(II)。;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."/>
