Hydrosulphite (HSO 3 − ), as a common and important chemical reagent, is widely used in everyday life, however excessive use and abuse of HSO 3 − can cause potential harmful effects on the environment and in biological health. In this paper, we describe the design and preparation of a colorimetric and ratiometric fluorescence probe for the visual detection of HSO 3 − (excitation wavelengths were, respectively, 336 nm and 520 nm). This method showed some advantages including simple preparation, high selectivity, fast response, and significant colour and fluorescence ratio (F 450 /F 594 ) changes in the presence of HSO 3 − . In addition, this probe was used successfully for the detection of HSO 3 − in real water samples and showed a good recovery rate range.
