Electrochemically pretreated screen-printed carbon electrodes for the simultaneous determination of aminophenol isomers

This study reports that disposable, electrochemically pretreated screen-printed carbon electrodes (SPCE*) can be employed for the simultaneous determination of aminophenol isomers in aqueous buffer solution. In sharp contrast to untreated SPCE, voltammetric studies indicate that the oxidation peak potential of each analyte in an aminophenol isomer mixture may be separated at the activated SPCE*. The individual oxidation peak currents are greatly...
