Abstract

A novel fluorescence nano-chemosensor for MnO₄^- anion has been developed by assembly of fluorescent aluminum complex of 8-hydroxyquinoline (8-HQ) within the channels of modied SBA-15 (SBA-SPS-QAl). The ordered porous structure of SBA-15 is still retained after hybridization by chemosensor material. A remarkable fluorescent quenching of SBA-SPS-QAl was attributed to the effect of MnO₄^- anion. The linear detecting range of the hybrid mesoporous chemosensor is 0.16-4.6 μmol L ^-1 of MnO₄^- anion and the lowest detection limit is 0.2 ng mL^-1 in the aqueous solution. SBA-SPS-QAl showed a selective and sensitive fluorescent quenching response toward MnO ₄^- ion in comparison with N₃^-, NO₃ ^-, CN^-, HCO₃^-, Cl^-, F^-, H₂PO₄ ^-, SO ₄^2-, Cr₂O₇^2-, IO ₃^- and I^- ions, which was because of the higher stability of its inorganic complex with permanganate anion.
