Variation of UV-Vis-NIR absorption of a cc-Fe3O4 NPs and b TD-Fe3O4 NPs with aeration oxidation time. Insets are photos of the suspensions corresponding to oxidation times at 0, 0.5, 1, 3, 5, 8, 10, and 12 h. All spectra and photos were obtained at the same Fe concentration. c Changes in anano of the oxidized cc-Fe3O4 NPs and TD-Fe3O4 NPs during the aeration oxidation. Error bars represent standard deviation from three independent measurements.
