A novel 1-hydroxy-2,4-diformylnaphthalene-based fluorescent probe was synthesized by a Knoevenagel reaction and exhibited excellent sensitivity and selectivity towards sulfite ions (SO) and bisulfite ions (HSO). The detection limits of the probe were 0.24 μM using UV-Vis spectroscopy and 9.93 nM using fluorescence spectroscopy, respectively. Furthermore, the fluorescent probe could be utilized for detection in real water samples with satisfactory recoveries in the range 99.20%104.30% in lake water and 100.00%104.80% in tap water by UV-Vis absorption spectrometry, and in the range 100.50%108.60% in lake water and 102.70%103.80% in tap water by fluorescence spectrophotometry.
