PROBLEM QUESTIONS OF TRACE ELEMENTS DETERMINATION BY INVERSION VOLTAMMETRY METHOD AND WAYS OF THEIR SOLUTIONS - article

Methods used for the determination of trace elements in food are examined. As a method for conducting numerous of studies are proposed inversion voltammetry. Advantages and isadvantages of this method are shown. Studies performed using voltammetric analyzers "ECOTEST" and "AVA- 3". According to the results of research is proposed to optimize the preparation of samples, as well as preparing the working surface electrodes, of which quality control is desirable to use the standard of cleanliness of the surface
