Deskripsi
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<sup>3+</sup> and Cr<sub>2</sub>O<sub>7</sub><sup>2−</sup> ions among a range of different species in aqueous media, consequently acting as a nanoporous chemosensor of Fe<sup>3+</sup> and Cr<sub>2</sub>O<sub>7</sub><sup>2−</sup> ions. An excellent linear relation was observed between the nanoporous chemosensor and ion concentrations, with acceptable detection limits of 2.43 × 10<sup>−6</sup> M and 3.96 × 10<sup>−7</sup> M for Fe<sup>3+</sup> and Cr<sub>2</sub>O<sub>7</sub><sup>2−</sup> ions respectively.
