Abstract:
9-Acridanone has been found in urban atmospheres. Four two-dimensional thin-layer Chromatographic methods have been described for the assay of this compound in urban atmospheres and in air pollution source effluents. Fluorimetric assay was done either directly on the plate or after elution. The best method involved two-dimensional separation on alumina-cellulose followed by elution and fluorimetric analysis of the acidic methanol solution. Urban atmospheres contain approximately 0.4 ng of 9-acridanone/m(3) of air.
