In this study, a simple and rapid sample pretreatment technique named pH-dependent continuous homogenous liquid–liquid extraction followed by gas chromatography-flame ionization detection has been developed for the extraction, preconcentration, and determination of four pesticides including diazinon, oxadiazon, bromopropylate, and fenazaquin in fruit juice and vegetable samples.
