- Description
- 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. 2019 The Royal Society of Chemistry.
