Analysis of Zinc- and Copper-Containing Tablets in Multicomponent Mineral Nutritional Preparations
Analýza tabliet s obsahom zinku a medi v polykomponentných minerálnych výživových doplnkoch
Práca bola zameraná na vypracovanie a optimalizáciu pracovných podmienok pri identifikácii a stanovení zinku a medi v polykomponentných minerálnych prípravkoch. Zinok Walmark® a TrikrátSedem FeCuZn modernou elektrochemickou analytickou metódou – galvanostatickou rozpúšťacou chronopotenciometriou (SCP) a nukleárnou analytickou metódou – rádionuklidovou röntgenofluorescenčnou analýzou (RRFA). Správnosť výsledkov analýz bola potvrdená porovnaním stanovení obsahov prvkov s použitím oboch analytických metód.

Overview
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:
