Abstract
Abstract The determination of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2-(2,4,5-trichlorophenoxy) propionic acid (Silvex) in water at the μg l-1 level is based on liquid/ liquid extraction and high-performance liquid chromatography. Sample preparation for water samples is simplified. The ranges of linear response are 50 ng to 60 μg for 2,4-D and 30 ng to 60 μg for Silvex. The average recoveries of 2,4-D at the 10 μg l-1 and 1 μg l-1 levels are 91% and 120%, respectively, while the average recoveries of Silvex at the 10 μg l-1 and 1 μg l-1 levels are 85% and 110%, respectively.
