posted on 2019-08-15, 07:17 authored by Chen Jiang, Yuewei Yao, Jingjing Meng, Cheng YaoA 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.
