A reliable and sensitive procedure for the simultaneous determination of trace levels of
copper and molybdenum is proposed. The complexing of copper (II) and molybdenum (VI)
with pyrogallol red (PGR) is analyzed by cathodic stripping differential pulse voltammetry
based on the adsorption collection of the complexes onto a hanging mercury drop electrode
(HMDE). The effect of chemical and instrumental parameters on the sensitivity and selectivity
were studied. Copper and molybdenum peaks potential were observed at about+ 0.13 ...
