Online Monitoring of Electrochemical Degradation of Paracetamol through a Biomimetic Sensor

Figure 2

Scheme of the coupling of the reactor with the FIA system. WE is the biomimetic sensor, AE represents the counter electrode, RE is the reference electrode. The D channel is used for the return of the electrolysis solution (sample) from the injector to the reservoir of the reactor, allowing maintain-sink condition in the experiments without loss of volume and thus avoiding errors in the calculation of the concentration of paracetamol, since the injected volume is only 75 μL in each sampling.
