For the first time, the possibility of using stripping voltammetry for the simultaneous determination of aflatoxins C1 and N1 on a glassy-carbon electrode has been shown. +e influence of various factors (F[upsilon], [tau][upsilon], w, and the nature of the background electrolyte) on the potential and magnitude of the oxidation current of mycotoxins has been estimated. Working conditions for voltammetric determination and reproducibility of analytical signals for two mycotoxins have been selected. +e mutual influence of aflatoxins C1 and N1 on the value of analytical signals in their simultaneous presence has been studied. It has been found that, in the range of their detectable contents, the presence of aflatoxin C1 reduces the analytical signal of aflatoxin N1 by 45-50%, but the linearity of the calibration dependence is preserved. +e content of aflatoxin N1 in determination of aflatoxin B1 does not exert a significant effect in the range of 10-15%. Based on the results obtained, a procedure has been proposed for determining the content of aflatoxins C1 and N1 in their joint presence in milk by voltammetry in the concentration ranges 2•10-3-:2•101 mg/dm3 and 2•10-4-:2•102 mg/dm3 , respectively (Sr not more than 18%).
