文摘
- •
Mesoporous silica/polyacrylamide nanocomposite adsorbent was prepared by UV-graft polymerization.
- •
Polyacrylamide was successfully grafted onto the silanized mesoporous silica.
- •
The Hg(II) adsorption capacity of the nanocomposite was as high as 177 mg g−1 after 1 h at RT.
- •
Adsorption process was found to fit pseudo second order kinetics and exothermic.
