摘　　要：用荧光光谱法检测建立了非水体系中蒽和芘的测试方法,蒽和芘的检测线性范围分别为5.6×10-9—2.8×10-6mol/L和4.9×10-8—1.47×10-6mol/L,相关系数为0.99959和0.99822,检出限分别为0.356ng/mL,5.230ng/mL,回收率分别为86.61%—98.66%和96.60%—115.80%。考察了常见离子、时间以及温度对荧光强度的影响,结果表明,常见离子对分析检测干扰均不大,可忽略,在2h、5—55℃温度范围内,对荧光强度影响较弱,故此分析检测方法对温度的适应范围较宽。方法可直接用于食品、饮料、酒产品等非水体系中的蒽和芘的测定。Fluorescence method was applied to the determination of anthracene and pyrene.The calibration curve linear ranges of anthracene and pyrene were 5.6×10^-9—2.8×10^-6mol/L and 4.9×10^-8—1.47×10^-6mol/L,respectively.Correlative coefficient was obtained as 0.99959 and 0.99822.The effect of common ion,temperature and time on the fluorescence intensity were studied.The no interference of common ions were for determination.Under the experiments conditions of 2 hours,5—55℃,the intensity of fluorescence was stable.Therefore this method has a wide range for temperature.can be used to detect anthracene and pyrene straight in non water system such as food,drink and liquor.
