Study of Voltam-metric Behavior of T-2 Toxin on Carbon-Containing Electrodes Analysis
Voltammetric behavior of T-2 toxin on carbon-containing electrodes and the effect of composition and pH of the base (supporting) electrolyte on the value of the analytical signal ofT-2 toxin are studied. The optimum pH of background electrolyte ranges within 3.5 - 5.5. We evaluated the effect of chemical adsorption on the peak current ofT-2 toxin electroreduction (the share of chemical adsorption is about 70%) and specifies conditions of voltammetric determination of T-2 toxin. The correctness of the results is confirmed in spiking test, the error of determination within a concentration range of 0.05 - 60 mg/dm<sup>3</sup> is 15 - 20 %.
