摘要: Excess iron and its toxic dye Naphthol Green B is a threat to aquatic environment human health. Therefore, effective detection remediation of ferric ion in aqueous system necessity. In our paper, bring out synergy dual functions sensing extraction/removal by same material, new ionophore based functionalized silica material (SiO2@Nap) was synthesized immobilization bis (tetradentate) naphthalene ligand on surface. Physicochemical properties the adsorbent were studied scanning transmission electron microscopy, atomic force XRD, FT-IR, thermo-gravimetric analysis elemental (CHN) analysis. The selective studies SiO2@Nap towards presence 17 other relevant metal ions evaluated through fluorescence quenching phenomenon which gives limit value 74 ppb (1.31 μM). adsorption for assessed view effect solution pH, extraction efficiency (99%), capacity (79 mg/g) isotherms. This can be recycled upon simple acid-base treatments further usage after recovery supported reversibility studies. strong affinity enabled this remove containing industrial with 99.5% recyclability. Adsorption, striping regeneration reveals that recyclable extracting cum sensory probe ions.
