NOVELTY - An acetaminophen electrochemical detection method involves preparing poly-3.4-dioxoethylenethiophene/graphene oxide/glassy carbon electrode (PEDOT/GO/GC electrode) by mixing pure 3,4 ethylenedioxythiophene monomer in graphene oxide ultrasonically for half an hour to obtain mixed solution. The glassy carbon electrode is placed in a mixed solution to obtain PEDOT/GO/GC electrode. The electrode is placed in a buffer solution, followed by adding acetaminophen, and using the electrode to detect acetaminophen electrochemical response. USE - Method for electrochemical detection of acetaminophen. ADVANTAGE - The method enables electrochemical detection of acetaminophen with better repeatability and high stability in a rapid manner. DETAILED DESCRIPTION - An acetaminophen electrochemical detection method involves preparing poly-3.4-dioxoethylenethiophene/graphene oxide/glassy carbon electrode (PEDOT/GO/GC electrode) by mixing pure 3,4 ethylenedioxythiophene monomer in graphene oxide ultrasonically for half an hour to obtain mixed solution. The glassy carbon electrode is placed in a mixed solution at a potential range of 0.2-1.2 V for cyclic voltammetry polymerization of 5-30 laps, and cyclic volt-ampere scanning speed at 100 mV/second to obtain PEDOT/GO/GC electrode. The electrode is placed in a buffer solution with pH of 2.8-7.0, followed by adding acetaminophen, using cyclic voltammetry scanning rate of 100-300 mV/s and the electrode to detect acetaminophen electrochemical response.
