摘要：

Tannic acid was found to inhibit chemiluminescence of the luminol-H2O2 reaction catalyzed by Cu2+. The mechanism of inhibition was investigated by chemiluminescent spectra, UV-visible spectra and variation of reaction conditions. A Row injection method has been developed for the determination of tannic acid based on the inhibition of the chemiluminescence of the luminol-H2O2-Cu2+ system by tannic acid. The method is simple, selective and sensitive with a detection limit of 9x10(-9) mol/l. It is effective to determine tannic acid in the range of 7x10(-8)-1x10(-5) mol/l. The variation coefficient of eleven determination for 6x10(-7) mol/l tannic acid is 2.5%. The method has been successfully applied to the determination of tannic acid in real Chinese gall and hop pellets samples. (C) 1998 Elsevier Science B.V.
