In this studythe selective determination of tannic acid (TA) was performed using a glassycarbon (GC) electrode modified with 1-Benzoyl-3-(pyrrolidine) thiourea (PrTu).PrTuwas deposited on the GC electrode in nonaqueous media by cyclicvoltammetry. PrTu-GC electrode demonstrated an electrocatalytical effect on theoxidation of TA using differential pulse voltammetry (DPV) method in 0.1 MBritton Robinson (BR) buffer solution of pH 2. Under optimum conditions linearcalibration graphs were obtained over the TA concentration range 2.0×10−6 to4.2×10−5 M. The detection of limit (LOD) was found as 0.6 µM. The proposedelectrode was applied to the determination of TA in tea sample withsatisfactory results.
