Abstract A novel imidazolium-based ionic liquid (IL), covalently bound to catechol (CA) groups by carbodiimide-mediated coupling reactions, was synthesized and used as the electrochemical sensing probe for dihydronicotinamide adenine dinucleotide (NADH). The thin layer of the CA-functionalized IL (IL-CA) at the screen-printed carbon electrode (SPCE) exhibited a stable redox couple originating from the catechol/quinone at the terminus. The redox-active film-modified electrode exhibited high and p...

In this study, we report a simple, low-cost and rapid electrochemical sensor based on the anodically pretreated screen-printed carbon electrodes (SPCE*) for the determination of pyrogallol in pH 7.0 buffer solutions. Cyclic voltammetric studies show that SPCE* lowers overpotentials and improve electrochemical behaviour of pyrogallol, compared to untreated SPCE. All experimental parameters were optimized to improve voltammetric responses; excellent analytical features were achieved by flow-inject...

Abstract 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 increased by first-order derivative t...
