ABSTRACT
A novel flow injection chemiluminescent enhancement method for the determination of tannic acid based on luminol-KIO4-Mn2+ system is developed. The method is simple, rapid and effective to determine tannic acid in the range of 3.0×10-8~5.0×10-6 mol/L with a detection limit of 9×10-9 mol/L. The relative standard deviation is 1.5% for the determination of 1.0×10-6 mol/L tannic acid (n=11). The mehtod has been applied to determine the content of tannic acid in Chinese gall with satisfactory results.
