文摘
- •
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.
