Determination of patulin in drinking water by flow-injection chemiluminescence system of luminol and Potassium ferricyanide

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 5×10-3～1mg/L under the optimal experimental condition.The limit detection of patulin was 4.6×10-4mg/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.
