Abstract

Sixteen organochlorine pesticides extracted out from the crops and cleaned by solvent-solvent partitioning and Florisil column chromatography were determined by gas-liquid chromatography. The majority of the pesticides were well separated by being eluted through 5% QF-1 column and some of them through 3% OV-17 column and 2.596 DC-200/2.5% QF-1 column, and the eluted pesticides were detected by $^{63}Ni$ electron capture detector. The linear calibration curves were obtained for the most of pesticides while some curves were slightly deviated from the linearity. In the determination of 16 pesticides added to thirteen kinds of crops, the recoveries were showed over 85% for the most cases and the relative standard deviations of 5 analyses were less than 12.1%. The results were within the criteria of the AOAC method.
