We used an effective electrochemical sensor for the determination of imipramine at pH 7.2 using a carbon nanocomposite electrode. The electrode has been designed by incorporation of montmorillonite nanoclay into the carbon ionic liquid electrode. The high sensitivity of 1.714 μA (μM)-1, two linear calibration ranges of 0.1–2 μM and 2-40 μM, and detection limit of 19 nM were achieved. The relative standard deviations (RSDs) were 2.73% (n=7, 2 μM), 2.97% (n=4, 2 μM), respectively. Thus, this modified electrode was further applied to the determination of imipramine in urine sample.
