A New Fast Response Colorimetric And Fluorescent Probe For The Detection Of Bisulfite And Its Application On Test Strips
INTERNATIONAL JOURNAL OF ENVIRONMENTAL ANALYTICAL CHEMISTRY(2020)
摘要
A new carbazole-based colorimetric and fluorescent probe CBB for the detection of bisulfite (HSO3-) has been developed via nucleophilic addition reaction. Probe CBB can detect HSO3- with excellent sensing properties including high selectivity and sensitivity, fast response (5 s). More importantly, probe CBB system not only can be applied to monitor HSO3- in environment with excellent solid properties based on test strips but also can be used for the detection of HSO3- in real-water samples with satisfactory results.
