| Abstract: | A gas-liquid chromatographic procedure is described for determining of residues of Isofenphos and Optunal in wheat and vegetable.The extract of the plant tissue is purified by addition of mixed absorbent,so that the procedure was simlified.Measurement is accomplished by gas-liquid chromatography using flame photometric detection. Recovery is 89%￣106%,Detection limits of Isofenphos and Optunal are 3. 8-×10-11g·s-1 and 4.0×10-11g·s-1respectively. |
