Abstract A novel CL method for the determination of tannic acid (TA) was established based on TA inhibition of the chemiluminescence (CL) emission of the luminol–hydrogen peroxide CL system catalysed by tetrasulphonated manganese phthalocyanine (MnTSPc) under alkaline conditions. The peak height is proportional to the natural logarithm of concentration of TA in the range 1.0 × 10 −7 –3.0 × 10 −10 mol/L with a detection limit of 5.6 × 10 −11 mol/L and the relative standard deviation was 2.5% for the determination of 1.0 × 10 −8 mol/L TA ( n = 11). The proposed method has been successfully applied to the determination of TA in Chinese gall and industrial wastewater. Copyright © 2006 John Wiley & Sons, Ltd.
