dc.description.abstract© 2022 Wiley-VCH GmbH.A square-wave voltammetric method was developed for the determination of creatinine using glassy carbon electrode functionalized multi-walled carbon nanotubes and doped with copper. Since the creatine-creatinine balance is dependent on pH, the linear responses at either pH 4.0 or 7.0 were evaluated allowing versatility in application, covering analyte concentration from limit of quantification (0.3 μmol L−1) up to 1.200 μmol L−1 (pH 4) or 660 μmol L−1 (pH 7). Electrode is simple to prepare and robust for routine analysis and it was used for the determination of creatinine in urine after simple thin-layer separation procedure to avoid interference from creatine.
