Correction: Synthesis of TiO2–Fe/Fe3O4 photocatalyst using iron rusty waste as Fe source for removal Pb(II) in water media under visible light with good separable property

This research studies on the visible photocatalytic improvement and separable ability of TiO2 by Fe doping and Fe3O4 magnetizing from iron rusty waste. The doping and magnetizing were performed by hydrothermal and precipitation methods, respectively. The Fe doped TiO2 (TiO2–Fe) prepared was magnetized with Fe3O4 having fraction of 33.3 wt
