Figure 2: Characterization of CoFe2O4 and CoFe2O4@MIL-100(Fe).

From: CoFe2O4@MIL-100(Fe) hybrid magnetic nanoparticles exhibit fast and selective adsorption of arsenic with high adsorption capacity

Figure 2

(A) FTIR spectra of (a) CoFe2O4 and (b) CoFe2O4@MIL-100(Fe); (B) TGA and (C) magnetic hysteresis curves of (a) CoFe2O4, (b) MIL-100(Fe), and (c) CoFe2O4@MIL-100(Fe); (D) XRD patterns, (E) N2 adsorption-desorption isotherms, and (F) DFT pore size distributions of (a) CoFe2O4, (b) MIL-100(Fe), (c) CoFe2O4@MIL-100(Fe), and (d) CoFe2O4@MIL-100(Fe) after the adsorption of As(V) [10 mL of 100 mg L−1 As(V) solution treated with 5 mg of the adsorbent]. All of the characterizations demonstrated that the MIL-100(Fe) shell was successfully coated on the surface of CoFe2O4 and that the hybrid adsorbent was highly stable.
