摘要:
A "turn-on" fluorescein-based probe for sulfite detection has been established employing SO32- promoted levulinyl cleavage and concurrent generation of fluorescein. The synthesized probe exhibits high SO32- selectivity over fourteen other anion ions, and the satisfactory detection limit was 0.80 mg/L in aqueous media containing co-solvent CH3CN (1%, v/v). The probe is successfully applied for the detection of sulfite in white wine. (C) 2013 Published by Elsevier B.V.
