Determination of Tannic Acid Using Silica Gel Modified Carbon Paste Electrode
Original language description
In this paper, silica gel modified carbon paste electrode (Si-gel/CPE) was used for the determination of tannic acid (TA) by anodic stripping differential pulse voltammetry (ASDPV). The influences of pH values, amount of silica gel, accumulation potential and time on the signal enhancement of TA were optimized, and a novel electrochemical method for the determination of TA was reported. The currents obtained from ASDPV measurements at optimum conditions were linearly correlated with the concentration ofTA. Calibration curve was obtained for TA concentrations in the range of 1 - 1000x10(-9) mol l(-1). The limit of detection was found to be 0.3x10(-9) mol l(-1). The results from TA measurements by Si-gel/CPE were in good agreement with those obtained from the standard spectrophotometric method.
