基于四磺基铝酞菁 (AlS4Pc) 在阳离子表面活性剂存在下发生诱导缔合而导致体系荧光猝灭，而在乙醇存在下AlS4Pc解聚而使体系荧光恢复的原理，建立了测定白酒中乙醇含量的新方法。方法的线性区间为0.5%～90%(V/V)乙醇，检测限为0.48%(V/V)。本法已应用于实际酒样中乙醇的直接测定，结果满意

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.
