The objective of this work is to compare the adsorption properties
of functionalized amorphous silica gel to those of ordered
mesoporous silica, aiming for future applications in water treatment.
The adsorbents for Hg(II) were prepared using silica gel
and MCM-41 as starting materials for surface modification. 2-(3-(2-aminoethylthio)propylthio)ethanamine [22]was chosen as
the ligand due to the presence of sulfur and nitrogen donor atoms,
the ease of preparation and the high yield of the reaction. The
adsorption properties of the modified materials were investigated
using a batch method.
