Mineral: |
Ferrihydrite |
Reference: |
AFPMA10 |
Preparation: |
synthesized following the procedure proposed by Cornell and Schwertmann, 1996 [1]; a 0.1 M Fe(NO3)3 solution was brought to pH 8.0 through dropwise addition of a 1 M NaOH solution; obtained dispersion of ferrihydrite was then aged at 20 °C for 48 h, and then dialyzed until the conductivity was lower than 10 µS/cm; freeze-dried in order to obtain a dry powder. |
Crystallinity: |
nanoparticles exhibit a strong aggregation state with particle diameters smaller than 10 nm |
Sample characterized via: |
☑ Transmission electron microscopy (TEM)
☑ X-ray Diffraction (XRD)
