Abstract
Fluorescence quenching of 9-amino acridine hydrochloride (9-AAH) by ammonia was found to be extremely efficient. Quenching data were analyzed using the Stern-Volmer relation. The method offers a limit of detection of 0.1 ppm over a useful range of 0 - 10 ppm. Fluorescence of the indicator 9-AAH showed a little or no interference from acidic gases, such as SO2, HCl, and H2S. The finding is considered to be of potential utility for the development of a fiber optic ammonia sensor and other methods of its quantitative determination.
