| Abstract: | A method for determination of spirodiclofen residue in apple and soil has been developed.Spirodiclofen was extracted with acetonitrile,cleaned up by florisil on a solid phase extraction column and then determined by gas chromatography equiped with electronic capture detector(ECD).The average recoveries and relative standard deviation of the method were 82.11% to 100.36%,0.92% to 6.84% for apple sample,and 79.27% to 94.55%,1.89% to 8.57% for soil sample,respectively.The minimum detectable amount of spirodicl... |
