A square wave voltammetry (SWV) method for the determination of trace amounts of paracetamol at carbon
paste electrode modified with managanese (Mn-CPE) is proposed. The results showed that the Mn-CPE exhibited
excellent electro catalytic activity to paracetamol. A quasi-reversible redox process of paracetamol at the modified
electrode was obtained. The concentration of paracetamol and measuring solution pH was investigated. This
electrochemical sensor shows an excellent performance for detecting paracetamol with a detection limit of 6.8×10-10
mol.L-1 with the relative standard deviation of 2.0% (n=7). The sensor was successfully applied to the determination
of paracetamol in a real sample tablets with satisfactory results. .. View More»
