Abstract

The adsorptive stripping voltammetry with differential pulse cathodic through the use of a mixture of complexing agents dimethylglyoxime and oxine was used for an exploratory study simultaneously of ions cadmium, cobalt, copper, nickel, lead and zinc. Were obtained voltammograms of the 64 individual solutions used in planning and current data were submitted to principal component analysis (PCA), allowing to characterize the trends of the solutions of metal ions studied. The system can be described in eight principal components that explained 98.32% of variance. Since the first three principal components accumulated approximately 85.46% of the total variance.
