在常温下制备的铁磁碳包覆铁纳米颗粒（磁芯尺寸为15 nm，饱和磁化强度Ms=218 emu g(-1)，矫顽力Hc=62 Oe）通过碳壳物理吸附可有效去除废水中95%以上的Cr(VI)，远高于市售铁纳米颗粒。
Ferromagnetic carbon-coated Fe nanoparticles (core size of 15 nm, saturated magnetization of Ms=218 emu g(-1) and coercivity of Hc=62 Oe), fabricated at a mild temperature, demonstrate a strong ability to effectively remove more than 95 wt% of Cr(VI) in waste water via carbon shell physical adsorption, which is much higher than the commercially available Fe NPs.
