摘要
Using vanadium extraction tailings as an iron source and glucose as a template, hollow spheres of Fe2O3 were successfully synthesized via hydrothermal synthesis for methyl orange adsorption treatment. The phase and structure of the samples were characterized by XRD, SEM, BET, and TEM. The results showed that the synthesized Fe2O3 exhibited a single hematite phase with a diameter of about 0.8 - 1.2 mu m, the sphere wall was composed of nanoparticles and the specific surface area was 21.327 m(2)/g. The adsorption results showed the optimal conditions for methyl orange ( MO) adsorption: for 1.0 g/L of adsorbent and a reaction time of 4 h, the MO adsorption rate was 85.9 % and the MO adsorption capacity of HSF was much higher than that of traditional Fe2O3.
