Development of a Method for a Sensitive Simultaneous Determination of Dopamine and Paracetamol in Biological Samples and Pharmaceutical Preparations

Figure 6

Hydrodynamic amperometric response at rotating MWCNTs /GCE (rotating speed 2500 rpm) held at 0.4 V in PBS (pH 7) for simultaneous determination of DA and PAR by successive additions of (a) 3 μM DA, (b) 3 μM PAR, (c) 40 μM DA, and (d) 30 μM PAR. Insets: (B) plot of peak currents as a function of DA concentration. (C) Plot of peak currents as a function of PAR concentration.
