原始语种摘要: Abstract(#br)A simple one step solvotermal strategy using non-toxic and cost-effective precursors has been developed to prepare reduced graphene oxide (RGO)-Fe 3 O 4 non-nanocomposite for removal of Cr(VI). Compared with the nano-adsorbent, the RGO-Fe 3 O 4 hybrid particles with size larger than 100nm can reduce cell toxicity in water treatment processes. The structure, surface and magnetic characteristics of the non-nanocomposite were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET), and Vibrating sample magnetometer (VSM). The RGO-Fe 3 O 4 composite with the highest loading of Fe 3 O 4...
