| Abstract: | In this paper,common organic phosphorus pesticides in soybean were detected by liquid-liquid partitioning chromatography,and gas chromatography-flame photometric detector （GC-FPD） with secondary cleaning in neutral alumina.The recoveries of standard addition of organic phosphorus pesticides ranged from 92% to 109%,and there was a relatively excellent linear relationship in the range of 0.1—4.0 mg/L with the correlation coefficient of 0.991.The addition-recovery detecting limit was 0.005mg/kg. |
