Role of the anionic dopant of poly(3,4-ethylenedioxythiophene) for the electroanalytical performance: electrooxidation of acetaminophen

Electroanalytical detection of acetaminophen is found to be effective by means of thin film PEDOT/PSS-coated electrodes. The concentration range of linear response is established to be 50 μM dm−3 to 1 mM dm−3 in linear sweep voltammetry experiments and 5 μM dm−3 to 65 μM dm−3 in DPV experiments. The corresponding LODs are 10 μM dm−3 and 0.3 μM dm−3, respectively. PEDOT/PSS-coated electrodes are used to determine acetaminophen in four medications containing various additional components.
