Gas chromatographic determination of some modern pesticides in fruits.
A method was developed for determination for residual amounts of some modern insecticides, acaricides and fungicides in fruits. The pesticides were extracted with methanol and partitioned into chloroform. The extract was purified by column chromatography on sodium sulphate/Florisil/Celite/charcoal. Analysis by gas liquid chromatography with 63Ni electron capture detection was completed successively on a column (150 cm x 4 mm) with 3% SE-30 and a column (150 cm x 2 mm with 3% OV-17 liquid phase. Recoveries of 17 pesticides from fortified samples of apples ranged from 83.3% to 98.4% for a level of 0.1 mg/kg.
