Abstract
A functionalized silica sorbent is described. The sorbent comprises mesoporous silica nanoparticles having a surface functionalized with a conjugated system comprising an azole and a phenyl. The surface may be functionalized by a Cu-catalyzed click reaction. The nanoparticles have an average particle size of 10-80 nm, and may be used to adsorb phenolic contaminants from aqueous solutions.
