A gas-liquid chromatographic method for determining imazalil residues in citrus fruit

An electron capture gas-liquid chromatographic method is described for the analysis of the fungicide imazalil,^a 1-(β-allyloxy-2, 4-dichlorophenethyl)imidazole, in citrus fruit. Recoveries were 80–95% from citrus fruit fortified at 0.50–2.0 mg/kg, with a limit of detection of 0.01 mg/kg.
