摘　　要： 基于棒曲霉素对鲁米诺-铁氰化钾发光体系显著的增敏作用,结合流动注射技术,建立了一种快速检测棒曲霉素的方法。在最佳实验条件下,线性范围为5×10-3～1mg/L,检出限为4.6×10-4mg/L,RSD为2.6%(n=11)。此方法具有简便快速、自动化程度高、可在线检测的特点,可用于饮用水中棒曲霉素的应急预警检测。 Based on the enhancing effect of luminol-ferricyanide chemiluminescence system by patulin, a novel method for rapid determination of patulin was developed combined with flow injection technique.An excellent linear range for patulin determination was 5 ×10^-3-mg/L under the optimal experimental condition.The limit detection of patulin was 4.6 ×10^-4 mg/L and relative standard deviation for the determination was 2.6% （n = 11 ）.This method showed the advantages of simple operation, high degree of automation and could be used for on- line rapidly determination of patulin in drinking water.
