An adsorption differential pulse stripping method for the simultaneous determination of
molybdenum and copper based on the formation of their complexes with cupferron
(benzene, N-hydroxy-N-nitroso) is proposed. The optimum experimental conditions were
obtained 0.010 mM cupferron, pH 3.0, accumulation potential of− 0.15 V versus Ag/AgCl,
accumulation time of 60 s, scan rate of 10 mV s− 1 and pulse height of 50 mV. Molybdenum
and copper peak currents were observed at− 0.16 and+ 0.02 V, respectively. A principal ...
