Velkoska Markovska, B. Petanovska Ilievska, Aleksandar Markovski | Keywords: | NP-HPLC method, organophosphorus insecticide residues, apple juice samples | Issue Date: | 2022 | Publisher: | ECOLOGICAL MOVEMENT OF NOVI SAD | Conference: | XXVI International Eco-Conference, XII Safe Food, Novi Sad, Serbia, 21–23th September, 2022 | 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. | URI: | http://hdl.handle.net/20.500.12188/26148 |
