摘要：

Differential-pulse anodic stripping voltammetry with a mercury microelectrode was used for the determination of copper with ethylenediaminetetraacetic acid as complexing agent. Interactions between analytical factors and their optimal levels were investigated using two factorial designs and the steepest ascent method. The calibration graph, calculated by least median squares, guarantees the linearity of the proposed calibration. Characteristic curves for the operating detection limit were established.
