Determination of ametoctradin in plant residues and environmental samples by HPLC with an UV detector

Resumo

The study deals with the development of a method for the determination of ametoctradin by HPLC with UV detection. Samples were extracted with aqueous acetone and then purified by distribution between immiscible solvents and also on solid-phase extraction cartridges. The procedure was tested in the determination of ametoctradin in water in the range 0.001–0.01 mg/L, in soil, potato vine and potato tubers, salad, onion, cucumber, tomatoes, carrots, grapes, and grape juice in the range from 0.005 to 0.1 mg/kg, depending on the matrix. The average recoveries were 78−92% with RSD < 0.08%. The proposed procedure is applicable to the determination of ametoctradin in environmental samples and plant residues.
