dc.description.abstractA preanodized clay-coated screen-printed electrode (CCSPE) is used for the determination of arbutin (hydroquinone-beta-D-glucopyranoside) in cosmetic bleaching products by square-wave voltammetry. The peranodization process exhibits a marked enhancement in the current response of arbutin at the CCSPE. Compared to the performance at a preanodized SPE, the coating of clay was found to further improve the sensitivity and reproducibility. Under optimized conditions, the linear range for arbutin detection is up to 90 mu M (correlation coefficient=0.999) in pH 10.0 ammonium buffer with a detection limit of 0.18 mu M (S/N=3). The electrode can be either disposable or reused since renewal provides good reproducible surfaces. Quantitative analysis was performed by standard addition for the arbutin content in commercial available cosmetic bleaching products. (C) 2000 Elsevier Science B.V. All rights reserved.en_US
