METHOD FOR QUANTITATIVE DETERMINATION OF T-2 TOXIN BY DIFFERENTIAL VOLTAMMETRY Russian patent published in 2016 - IPC G01N27/48 

FIELD: chemistry.

SUBSTANCE: invention relates to analytical chemistry and can be used in pharmacokinetic analysis for control of agricultural products of vegetal origin. According to invention, T-2 toxin is transferred from a sample into the solution and voltammetric accumulation of mycotoxin in a stirred solution for 30 s at electrolysis potential (-0.5±0.05) v relative a saturated silver chloride electrode on the background of potassium nitrate (KNO₃), pH 4.0÷5.0, with subsequent recording of cathode peaks at scanning rate of 30 mV/s. concentration of T-2 toxin were determined by peak height in the range of E_n=(-1.25±0.35) in by standard addition method.

EFFECT: invention provides extending the range of determined concentrations of t-2 toxin and development of rapid evaluation of T-2 toxin for 30-40 minutes and possibility to use electrodes made of nontoxic material.
