An analytical method for the determination of imazamox in soils and maize plants

An HPLC method to analyze imazamox residues in three soil types and in maiz e plants is reported. The method allows for a rapid and quantitative detect ion of imazamox both in soils and maize plants. The limit of detection was 10 ng. Recoveries in soils were satisfactory and varied from 82.2% to 99.5% , depending on soil type and initial concentration, while in plants they we re slightly lower but still satisfactory. Its reproducibility and the accur acy make this method a selective and sensitive tool for routine analyses.
