A voltammetric sensor for determination of
paracetamol in the presence of morphine is described for
the first time. The synthesized CdO nanoparticles were
characterized with different methods such as scanning
electron microscopy (SEM) and X-ray diffraction (XRD).
The paracetamol and morphine peaks are separated ca.
0.37 and 0.65 V, respectively; hence paracetamol can be
analysed in the presence of morphine and more than 21
times of the current excess of paracetamol. The detection
limits for paracetamol and morphine were 0.07 and
0.1 mM, respectively. The sensor has been successfully applied
for the assay of the above compounds in real samples.
