| Abstract: | The electrochemical characteristics of paracetamol were studied by cyclic voltammetry and square wave voltammetry in the presence of microwave radiation,and a considerable current enhancement was observed for paracetamol.A new electrochemical method for the determination of paracetamol was established under microwave sensitization effect.Under the optimal conditions,there was a good linearity between the responsivity current and the concentration of paracetamol in the range of 0.2—80μg/mL（r=0.9966,n=7）.The linear regression equation was ip（μA）=1.92×103C（μg/mL）-29.4 with the detection limit of 0.05μg/mL,and the RSD was 0.82% for the paracetamol concentration of 4μg/mL for 10 parallel determinations. |
