In this work, a simple and sensitive method for the analysis of the pesticide o-phenylphenol (OPP) on citrus fruits was developed. OPP is extracted with dichloromethane by ultrasonication and derivatized with ferrocenecarboxylic acid chloride. Using ferrocene as a label, residues of OPP are
A HPLC-method is described for the determination of diphenyl, o-phenylphenol, thiabendazole, diphenylamine, and ethoxiquin in different fruits (detection limits: 0.1 mg/kg). The compounds are extracted with dichloromethane, and after concentration and filtration steps the determination is carried
Coupled-column liquid chromatography with fluorescence detection was applied to the determination of o-phenylphenol and bitertanol residues in orange and banana fruits. After extraction with a mixture of acetone, dichloromethane-petroleum ether, and ethyl acetate, an extract aliquot of 100 microL
