Abstract
This paper presents the application of a new, precise and accurate high-performance liquid chromatography (HPLC) method with ultraviolet-diode array detection (UV-DAD) for determination of some organophosphorus, phenoxycarboxylic acid and organonitrogen pesticide residues in water samples. The successful separation and quantitative determination of analytes were achieved using a LiChrospher 60 RP-Select B (125 x 4 mm, 5 µm) analytical column maintained at 25 °C and UV detection at 220 nm. The mixture of acetonitrile/water (55/45, V/V) was used as a mobile phase, with flow rate of 1 mL/min. The proposed method was successfully applied for the determination of investigated pesticides in water samples.
