Figure 7. AFM images of a malachite surface soaked in
1×10–4 M OHA solution for 60 minutes. A) the 5 µm × 5 µm
height image with a data scale of 20 nm B) the 3-D image C)
the section analysis and D) the deflection image with a data
scale of 5 nm. The 1 µm × 1 µm blank ‘window’ in the center of
the image is due to the removal of the adsorbate from mineral
surface under the intentionally applied large scan force

OHA solution for 10 minutes. A) the 2 µm × 2 µm height image
with a data scale of 20 nm B) the 3-D image C) the section
analysis and D) the deflection image with a data scale of 5 nm
