摘要：
Capillary zone electrophoresis (CZE) with on-column UV detection at 214 nm was used to detect and determine gold(I) and silver(I) cyanide complexes in alkaline cyanide solution. Under an applied voltage of 25 kV, dicyanoaurate(I) and dicyanoargentate(I) were separated in less than 6 min. Carbonate buffer was used and the separation of both anions was achieved using an anodic injection and cathodic detection scheme. Tle method was applied to the determination of gold and silver cyanide in ore samples. Quantitative analysis was possible and good agreement between CZE and atomic absorption spectrometric results was obtained.
