| Abstract: | The method was established for the determination of octachlorodipropyl ether(S-2) residue in edible fungi by GC.The samples were extracted with acetone and hexane,and purified by liquid-liquid partition sulfonation with H2SO4.The external standard method was adopted for the determination by μECD.Tests of recovery were made by addition of standard S-2 to the edible fungi samples at the concentration levels in the range of 0.005~0.05 mg/kg,and the recoveries were between 72.4% and 104.4%,with RSDs less than 7.86%.The results indicated the method had the advantages of rapidness and accuracy,and can be used for routine analysis and quality control in fungi samples. |
