Online Monitoring of Electrochemical Degradation of Paracetamol through a Biomimetic Sensor

Figure 5

Profile from the decay of the concentration of paracetamol obtained by the standard HPLC method (off-line) and by the on-line system proposed, as a function of the electrolysis time. Electrolysis was conducted by applying 100 mA cm⁻² using 2.0 L of electrolyte solution of 0.1 mol L⁻¹ K₂SO₄ and 5.0 × 10⁻⁴ mol L⁻¹ FeSO₄·7H₂O containing 1.35 × 10⁻² mol L⁻¹ paracetamol.
