Abstract
This paper describes a new, precise and accurate normal-phase high-performance liquid
chromatography (NP-HPLC) method with ultraviolet-diode array detector (UV-DAD) for
determination of some organophosphorus insecticide residues in different apple juice samples.
The analyses were performed using a LiChrosorb CN analytical column (250 x 4 mm; 5 μm), a
mobile phase composed of n-hexane and dichloromethane with a volume ratio (80/20, V/V), a
flow rate of 1 mL/min, a constant column temperature of 25 ºC and UV detection at 220 and 270
nm. The obtained results showed that analysed apple juice samples did not contain detectable
residues of investigated pesticides.
