Abstract
A procedure for the determination of Cr-VI by differential pulse adsorptive stripping voltammetry (DPAdSV), using diphenylcarbazide (DPCI) as a comple xing agent, has been optimized. The selection of the experimental condition s was made using experimental design methodology, it was under these condit ions the calibrations were made, using a robust regression method which all ows the elimination of anomalous paints. The detection limit obtained was 3 .169 x 10(-9) mol dm(-3).
