摘要:
建立了一种通过改进的QuEChERS样品预处理方法和气相色谱—微池电子捕获检测器(GC/μECD)法快速测定土壤中毒死蜱残留量的分析方法,样品用含0.1%乙酸的乙腈超声提取,用适量N-丙基乙二胺(PSA)和C18填料净化,GC/μECD检测,外标法定量。结果表明,毒死蜱的响应在0.005~5.000 mg/L质量浓度范围内线性良好,相关系数r大于0.99,在0.01~0.50 mg/kg添加水平范围内,平均回收率为79.52%~95.59%,RSD为2.03%~6.92%,检出限(LOD)为0.000 4 mg/kg,定量限(LOQ)为0.005 mg/kg,基质效应对定量结果的影响可忽略不计。该方法操作简单,灵敏度高,干扰少,分析成本低,节省溶剂,能够满足土壤中毒死蜱残留检测的要求。
