摘要
稻田土壤经石油醚震荡提取,加PSA、C18、无水硫酸镁净化后,经UPLC农药残留检测,外标法定量,方法回收率在73.20-94.55%、变异系数4.31-8.37%、最低检出浓度分别为0.02mg/kg。
phoxim was extracted from Paddy soil with petroleum ether by shocking, and then added PSA、C18、anhydrous magnesium sulfate to purify. UPLC was used to detect the pesticide residue, external standard method was applied to quantify, the recovery was 73.20-94.55%, coefficient of variation was 4.31-8.37%, the minimum detectable concentration was 0.02mg/kg.
