- W2431831491 abstract "目的 建立工作场所空气中毒死蜱的溶剂解吸气相色谱测定方法.方法 采用硅胶管吸附空气中的毒死蜱,用90%甲苯和10%丙酮的混合液解吸后用带火焰光度检测器(FPD)的毛细管气相色谱法测定.结果 空气中毒死蜱浓度在0.22～14.22 mg/m3(以采集4.5 L空气样品计,相当于毒死蜱标准溶液在1-64μg/ml)时,回归方程Y=612.82X-60.59,相关系数r=0.9999,检出限为0.06 mg/m3.平均解吸效率89.67%,采样效率94.0%,样品在室温下至少可以保存15 d.结论 该方法适用于工作场所空气中毒死蜱浓度的测定。" @default.
