摘　　要：以纸质食品外包装中荧光增白剂为检测对象,对其样品前处理工艺进行了探讨。考察了浸取溶剂种类、用量、提取温度及样品面积等对荧光增白剂提取效果的影响,通过HPLC法对提取的荧光增白剂组分进行对比分析。在样品量一定的情况下,得到了溶剂种类、用量、温度及样品碎片面积的优化工艺。The sample pretreatment process of fluorescent brightener was disscussed,taking the fluorescent brightener in paper-based food packaging as the sampling object. The effects of types,dosage,extracting temperature of leaching solvent and sample areas on the result of extracting fluorescent brightener were studied. HPLC was used to analyse the extracted fluorescent brightener component. In a certain amount of sample,the optimum process of types,dosage,temperature of solvent and sample area fragments was obtained.
