ON-LINE ELECTROLYTIC DISSOLUTION OF SOLID METAL SAMPLE AND DETERMINATION OF COPPER IN ALLOY BY AAS

摘要

On-line dissolution of solid metal sample can be carried outby electrolysis under the control of flow injection analyzer(FIA),andthe dissolved sample can be transferred to atomic spectrometer for thedirect analysis.The hyphenated technique of FIA on-line electrolyticdissolution of alloy and atomic absorption spectrometer(AAS)detectionis developed.The research is focused on the effects of electrolytecomposition and electrolysis parameters on the sample dissolving,aswell as the quantitative analysis of Cu in Al alloy samples.
