Paper Abstract

Fluorescence quenching of 9-amino acridine hydrochloride (9-AAH) by ammonia was found to be extremely efficient. Quenching data were analyzed using the Stem-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 mtereference from acidic gases, such as SO2, HC1 and H2S. The fmding is considered to be of potential utility for the development of a fibre optic ammonia sensor and other methods of its quantitative determination.
