摘要：

A novel analytical procedure for the determination of 2,4-dichlorophenoxyacetic acid in soil samples has been developed. The acid is extracted from the soil and simultaneously esterified in situ to its methyl ester by means of a benzyltrialkylammonium-type organic solubilizer. Quantitation was carried out by capillary gas chromatography with an electron capture detector. Recovery was over 96%. The procedure offers possible extension to other chlorophenoxy acids.
