摘要:

The simultaneous determination of Au(Ⅲ) and Cu(Ⅱ) by atomic absorption spectrometry[1,2], X-ray fluorescence[3] and differential-pulse polarography[4] have been reported. The apparatus used in spectrochemical analysis are complex and expensive. The method reported in reference[4] involves a poisonous electrode-DME(dropping-mercury electrode) and unsatisfied performance with the detection limit. We had reported the determination of trace Au(Ⅲ) or Cu(Ⅱ) by a sensitive tripping voltammetry with solid electrode[5], but there is no report about the simultaneous determination of trace Au(Ⅲ) and Cu(Ⅱ) by stripping voltammetry ever since.
