Sensitive Voltammetric Determination of Atenolol at Multi-walled Carbon Nanotubes Modified Glassy Carbon Electrode

R.N. Hegde, P. Chandra and S.T. Nandibewoor

Abstract:
This study describes the excellent electro-catalytic activity towards voltammetric oxidation of atenolol at Multi-walled carbon nanotube (MWCNT)-modified glassy carbon electrode and its determination. Compared to bare glassy carbon electrode, the MWCNT-modified glassy carbon electrode exhibited an apparent shift of the oxidation potential to the less positive direction and a marked enhancement in the current response of atenolol. The electro-catalytic behavior was further exploited as a sensitive detection scheme for the atenolol determination by differential-pulse voltammeter. Under optimized conditions, the linear range and detection limit are 2.0x10-7 to 6.0x10-6 and 2.34x10-8 M, respectively for atenolol. The proposed method was successfully applied to atenolol determination in pharmaceutical samples and urine, without any preliminary treatment.
