ABSTRACT
The optimal conditions for the separation and quantification of pesticides of the following classes by capillary electrophoresis are found: aryloxy carboxylic acids, sym-triazines, triazinones, chloroacetamides, urea derivatives, neonicotinoids, carbamates, triazoles, dithiocarbamates, imidazoles, benzimidazoles, and organophosphorus compounds. Procedures are proposed for the determination of pesticides in surface, well, and drinking water after their preconcentration by solid-phase extraction on preconcentration cartridges Oasis® HLB 3cc/60 mg. The recovery of pesticides was 80-95%. The lower limits of the analytical range for pesticides in water with preconcentration was 0.2-1 μg/L; the relative standard deviation did not exceed 10%.
