ABSTRACT
A new fluorimetric method was developed for the determi nation of ethanol in alcoholic beverage. The method is based on the principle that tetrasubstituted sulphonated aluminum phthalocyanine (AlS4Pc), a red-r egion fluorescent reagent, is induced to associate in the presence of cationic s urfactant, cetyltrimethylammonium bromide (CTMAB), thus its fluorescence is quen ched, and then the aggregate is disaggregated by the a ddition of ethanol and the fluorescence is recovered. This method has a linear determination range of 0.5%~90.0%(V/V), the detection limit is 0.48%(V /V). The method has been used to determine real alcoholic beverage samples w ith satisfactory results.
