A carbon paste electrode (CPE) modified with ferrocenedicarboxylic acid (FCD) and carbon nanotubes (CNTs), was prepared for determination of epinephrine (EP) in the presence of acetaminophen (AC). The electrochemical response characteristics of the modified electrode toward EP and AC were investigated by differential pulse voltammetry (DPV). The results showed an efficient catalytic role for the electro-oxidation of EP and AC, leading to a remarkable peak resolution (similar to 250 mV) for two compounds. Under the optimum conditions, the calibration curve for EP was obtained in the range of 5.0x10(-8) to 4.5x10(-4) M. The proposed method was applied to determination of EP and AC in real samples and the obtained results were satisfactory.
