Abstract

A highly selective and sensitive fluorescent probe for the determination of Hg ²⁺ ions is reported using substituted mercaptotriazole functionalized TiO ₂ nanoparticles (MMT@TiO ₂ ). The functionalized TiO ₂ nanoparticles were characterized by UV-vis spectrophotometric, spectrofluorometric, FT-IR, FT-Raman, XPS, TEM, SEM, EDAX and P-XRD analyses. The interaction of Hg ²⁺ ions with functionalized MMT@TiO ₂ induced aggregation of nanoparticles causing chelation enhanced fluorescence. The limit of detection and limit of quantitation for the determination of Hg ²⁺ ions were found to be 2.18 × 10 ^-10 M and 6.61 × 10 ^-10 M, respectively. The method developed was successfully applied for the determination of Hg ²⁺ ions in environmental samples.
