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.

        Key words: trace elements – galvanostatic stripping chronopotentiometry – X-ray fluorescence analysis
