Abstract A selective and sensitive method to determine of cadmium and zinc in water and
alloy samples is proposed by adsorption stripping differential pulse cathodic voltammetry.
The complexes of cadmium and zinc ions with xylenol orange (XO) are analyzed based on
the adsorption collection onto a hanging mercury drop electrode (HMDE). The variation of
peak currents with pH, XO concentration, potential and time of adsorption plus the
instrumental parameters such as scan rate and pulse height were optimized. The ...
