Voltammetric Determination of Metamizol Sodium in Pharmaceutical Tablets at Polypyrrole-Carbon Nanotube Modified Electrodes
Öz
Poly pyrrole-carbon nanotube (PPy-CNT) composite electrodes were prepared with ultrasonication assisted
pulsed polymerization technique. This technique possesses both advantages of ultrasonication and
electrochemical polymerization. PPy-CNT composite was modified on the bare glassy carbon electrode (GCE)
surface easily with pulsed deposition technique that provide more catalytically active surface compared to the
bare GCE towards metamizol oxidation. Resulted electrode was characterized by scanning electron microscopy
and used for investigation of metamizaol in pH:2 Britton-Robinson buffer solution. In the differential pulse
voltammetric determination, the linear range was found as 5-500 mg L-1 with a detection limit of 1.6 mg L-1
.
The overall results showed that PPy-CNT electrode has an excellent sensitivity, selectivity and anti-fouling
properties for the voltammetric determination of metamizol. PPy-CNT/GCE sensor was applied succesfully to
the determination of metamizol in novalgine sample.
