Abstract
In order to develop the multi-residue purification method for 180 pesticides commonly used in Korea, many analytical methods on individual and multi- pesticide residues in the agricultural commodities and food product were examined. Through the modification of adsorption chromatographic methods used in Europe, the United States and Korea, the Florisil and silica-gel chromatographic systems were developed. Through these purification systems, elution profiles for all pesticides were examined. As the results, 145 pesticides were recovered in the range of 70-120% in Florisil clean-up system. The distribution of pesticides in the elution profile was 12 pesticides in the first fraction, 76 pesticides in the second fraction, 81 pesticides in the third fraction, 60 pesticides in the fourth fraction and 30 pesticides in the last fraction. And, in silica-gel system, 137 pesticides were recovered in the range of 70~120%. The distribution of pesticides in the elution profile was 22 pesticides in the first fraction, 59 pesticides in the second fraction, 102 pesticides in the third fraction, 46 pesticides in the fourth fraction and 8 pesticides in the last fraction.
