Abstract EN
A glassy carbon electrode modified with a Nafion/MWCNTs composite is shown to enable the determination of codeine using differential pulse voltammetry in phosphate buffer of pH 3.0.
At a preconcentration time of 15 s, the calibration graph is linear in the 0.5 µM (0.15 mg·L−1) to 15 µM (4.5 mg·L−1) concentration range with a correlation coefficient of 0.998.
The detection limit at a preconcentration time of 120 s is as low as 4.5 μg·L−1.
The repeatability of the method at a 0.6 μg·L−1 concentration level, expressed as the RSD, is 3.7% (for n=5).
The method was successfully applied and validated by analyzing codeine in drug, human plasma, and urine samples.
