Abstract :
A multi-walled carbon nanotubes (MWNTs) film modified glassy carbon electrode (GCE) has been fabricated and showed potent electrocatalytic activity toward the electrochemical oxidation of salbutamol sulfate in phosphate buffer solution (pH=7.4). The linear dependence between the oxidation peak current of salbutamol sulfate and its concentration was observed in the range from 5.0 - 25 mumol/L with a detection limit of 1.0 mumol/L. The electrode possessed a nice recovery of 97.2 - 104.4% with good reproducibility and stability for detection of salbutamol sulfate aerosol samples, indicating that it was a feasible method for determination of salbutamol sulfate in actually pharmaceutical samples.
