摘要
The optimal conditions for the separation of pesticides of the following classes: phenoxy carboxylic acids, sim-triazines, triazinones, chloroacetamides, urea derivatives, neonicotinoids, carbamates, triazoles, imidazoles, benzimidazoles, and phosphorus organic compounds by micellar electrokinetic chromatography have been selected. A method for determining 27 polar pesticides in soil using QuEChERS sample preparation has been developed. The recovery of pesticides was from 31 to 104%. The lower limits of the found pesticide concentrations in soil taking into account preconcentration were 0.01-0.4 mg/kg. The relative standard deviation of the results of analysis does not exceed 10%.
