Square-wave voltammetric determination of pantoprazole using ex situ plated antimony-film electrode

The antimony film electrode (SbFE) was used for expedient measurement of pantoprazole, i.e. an impor-tant pharmaceutical substance. The SbFE was prepared ex situ on a supporting glassy carbon electrode andemployed in direct square-wave voltammetric mode. After studying and optimizing several experimen-tal parameters, the electrode exhibited an auspicious electroanalytical performance in Britton–Robinsonbuffer solution with the calculated LOD of 9.1 × 10−7mol L−1and an excellent reproducibility with theRSD of ±0.8%. Actual applicability of the SbFE in organic electroanalysis was demonstrated via measuringlow concentration levels of pantoprazole in a real pharmaceutical dosage form.
