摘要：
The potential of a flow-injection-zone sampling system equipped with a diode-array spectrophotometric detector for the simultaneous determination of metal ions in mixtures was studied. Zone sampling was accomplished by using a commercially available, variable-volume, dual-channel bypass injection valve. The mixed spectra were recorded at the maximum of the flow-injection peaks and were resolved into the individual components by using a partial least-squares method. The method was applied to the determinations of Cu(II) and Zn(II) in mixtures with 4-(2-pyridylazo)resorcinol as reagent.
