摘　　要：以FeSO4.7H2O∶KBH4=1∶2(摩尔比)为固相介质,0.06 g/ml羧甲基纤维素水溶液为液相介质,固液比1∶2,调制成流变相体系反应2 h制备出包覆型纳米零价铁;采用XRD、TEM等手段对合成的纳米零价铁进行表征。In this study,coated nano-iron particles were prepared by using rheological phase reaction method.FeSO4·7H2O and KBH4（molar ratio of 1∶2）were used as solid-phase media,and 0.06 g/ml carboxymethyl cellulose（CMC）solution as liquid medium.The ratio of solid/liquid was 1∶2.Nano zero-valent iron（ZVI）was prepared in the modulated rheological phase reaction system with a reaction time of 2 h.The nano ZVI was characterized by XRD,TEM,etc.
