A preanodized screen-printed carbon electrode is used for the determination of kojic acid in cosmetic bleaching products by square-wave voltammetry. The preanodization process leads to a marked enhancement of the current response of kojic acid at the screen-printed carbon electrode. The linear range is up to 260 mu M in pH 10 Britton-Robinson buffer with a detection limit (S/N=3) of 0.17 mu M. The electrode has the advantages of low cost, of being easy to handle, and it can be either disposable or reused since the renewal gives a reproducible surface. Quantitative analysis for the kojic acid content in cosmetic products was performed by the standard addition method.
