| مستخلص: |
Selective determination of caffeic acid, was carried out by using Screen Printed Carbon Electrode (SPCE) to give a reliable, scalable, and inexpensive electrochemical method with enhanced analytical performance. SPCE was first activated by linear sweep voltammetry using KOH solution, followed by its electrochemical grafting with cyclodextrins. Britton Robinson buffer (BRB) solution having pH 8.1, demonstrated a clear electrocatalytic impact towards caffeic acid oxidation, which indicated a greater current response compared to the activated electrode in the cyclic voltammetric and square wave voltammetric (SWV) investigations. The SWV waves at the activated SPCE was used under ideal conditions to produce a linear calibration curve with detection limits of (LoD, 4 sb/m) and quantification limits of (LoQ, 11 sb/m) of 0.38 mM and 1.1 M, respectively.
