| Tartalmi kivonat: | In this study, a method for the determination of triclopyr in soil samples has been developed. The analyte was extracted with acidified acetonitrile, while the determination and quantification of triclopyr were performed by high-performance liquid chromatography (HPLC) with a diode array detection. Optimal HPLC-DAD conditions were: mobile phase acetonitrile and 0.1% H3PO4 (50:50), the flow rate of 0.9 ml/min, and 220 nm of wavelength. In terms of method validation, accuracy (expressed as recovery), linearity, precision (RSD) and LOQ were determined. Obtained results for the recovery using this method, at the three spiking levels, were 81-93%. Precision, expressed as RSD, was 9.1%, while the LOQ was 0.01 mg/kg. Therefore, it can be concluded that the proposed method could be applied for the analysis of triclopyr residues in the soil samples. |
