Abstract:
The aim of this study was to elaborate and optimize the working conditions for the identification and determination of zinc and copper present in the multicomponent mineral preparations Zinok Walmark and TrikrátSedem FeCuZn by a modern electrochemical analytical method--galvanostatic stripping chronopotentiometry, and a nuclear analytical method--X-ray fluorescence analysis. The proposed analytical methods were compared with each other and the obtained results concerning the quantity of determined elements were in good agreement.
