A Commercially Available 2-aminoanthracene Fluorescent Probe for Rapid and Sensitive Detection of Hypochlorite in 100% Buffer Solution and its Application in Complex Water Samples

Hypochlorite (ClO^-), a crucial chemical in the living organism, engages in various physiological activities. However, high amounts of ClO^- result in oxidative damage. In this work, a commercially available 2-aminoanthracene (AA) was used to detect ClO^-. AA demonstrated distinct properties such as superior selectivity and rapid response (< 30 s) with a low detection limit (140 nM) towards ClO^- in 100% buffer solution. Furthermore, the probe exhibited a notable achievement by effectively identifying the presence of ClO^- in complicated water samples. In conclusion, AA offers an easy-to-use and accurate method for quantifying ClO^- in complex water samples.
