Abstract

A novel fluorescent sensor for the recognition of Hg2+ in aqueous media was developed by assembly of 2,6-bis(2-benzimidazolyl) pyridine to SBA-15 nanoporous silica. The synthesized materials were characterized by techniques such as XRD, FT-IR, N2 adsorption–desorption, and TGA. Investigation of fluorescence properties of prepared material revealed emission spectra having maxima at 396 nm following excitation at 353 nm. It was found that the fluorescence intensity of the SBA-15 functionalized material remarkably quenched in the presence of Hg2+ ions in the pH range of 6–8, showing high selectively toward mercury ion among the more common tested cations. The fluorescence titration studies confirmed the linear relation between the concentration of Hg2+ ion and the fluorescence intensity quenching, and the lowest detection limit was calculated as 2.6 × 10−6 M. © 2018, University of Tehran.
