Abstract
Differential-pulse anodic stripping voltammetry with a mercury microel ectrode was used for the determination of copper with ethylenediaminet etraacetic acid as complexing agent. Interactions between analytical f actors and their optimal levels were investigated using two factorial designs and the steepest ascent method. The calibration graph, calcula ted by least median squares, guarantees the linearity of the proposed calibration. Characteristic curves for the operating detection limit w ere established.
