The method was successfully applied for the extraction and determination of 2,4-D in several edible seeds and water samples.Īlesso M, Talio MC, Fernández LP (2017) Solid surface fluorescence methodology for fast monitoring of 2,4-dichlorophenoxyacetic acid in seed samples. The recoveries were in the range of 82.0–95.0 % with RSD values less than 7.2%. The limit of detection (LOD) and limit of quantification (LOQ) were 0.3 and 1.0 ng/mL, respectively. Under the optimized experimental conditions, calibration curve shows good linearity ( r 2 > 0.9957) and precision (RSD < 6.5%) in the concentration ranges of 1.0–10,000 ng/mL. The target analyte was successfully extracted by acetonitrile and sodium chloride as extracting solvent and salting-out agent, respectively. Affecting variables on the extraction efficiency of the 2,4-D, such as the solvent type and its volume, type of salt and its concentration, vortex time, and sample pH, have been investigated and optimized. ![]() Extraction was achieved based on salting-out phenomenon. ![]() Due to the polar nature of the 2,4-D molecules, LC analysis was performed on a CN stationary phase by using acetonitrile and acidic water as mobile phase. A simple, fast, and effective salt-assisted liquid-liquid extraction (SALLE) technique coupled with high-performance liquid chromatography (HPLC) was developed for determination of 2,4-dichlorophenoxyacetic acid (2,4-D) in water and edible seeds samples.
