Adsorption of Hg(II) from aqueous solutions using TiO2 and titanate nanotube adsorbents

- TiO2-P25, TiO2-SG and titanate nanotubes were compared as Hg adsorbents.
- Mercury uptake was significantly enhanced as pH increased up to pH 10.
- Porosity is not a crucial variable in the global Hg(II) adsorption rate.
- Titanate nanotubes exhibited net adsorption capacities higher than titania samples.
- TNT materials showed the smallest capacities normalized to surface area.
