SBA-Pr-Is-TAP Functionalized Nanostructured Silica as a Highly Selective Fluorescent Chemosensor for Fe(3+) and Cr(2)O(7)(2−) Ions in Aqueous Media

SBA-Pr-Is-TAP was synthesized via functionalization of SBA-15. The synthesized hybrid nanomaterial was characterized by various techniques including FT-IR, TGA, XRD, SEM, and BET. SBA-Pr-Is-TAP could precisely bind Fe(3+) and Cr(2)O(7)(2−) ions among a range of different species in aqueous media, co...

Sumario:SBA-Pr-Is-TAP was synthesized via functionalization of SBA-15. The synthesized hybrid nanomaterial was characterized by various techniques including FT-IR, TGA, XRD, SEM, and BET. SBA-Pr-Is-TAP could precisely bind Fe(3+) and Cr(2)O(7)(2−) ions among a range of different species in aqueous media, consequently acting as a nanoporous chemosensor of Fe(3+) and Cr(2)O(7)(2−) ions. An excellent linear relation was observed between the nanoporous chemosensor and ion concentrations, with acceptable detection limits of 2.43 × 10(−6) M and 3.96 × 10(−7) M for Fe(3+) and Cr(2)O(7)(2−) ions respectively.
