Abstract
目的 建立工作场所空气中磷酸三丁酯的采样和测定方法.方法 采用玻璃纤维滤纸采样,乙醚洗脱,气相色谱分离,火焰光度检测器(磷滤波器)检测.结果 该方法测定磷酸三丁酯的线性范围为7.2~720.0 μg/ml,相关系数为0.999 92,方法检出限为0.86 μg/ml,最低检出浓度为0.14 mg/m3(以采样空气样品体积30 L计算);加标回收率为99.8%~100.2%,批内精密度为4.0%~5.4%,批间精密度为2.0%~5.5%,采样效率为99.1%~100.0%.结论 该方法各项指标均达到GBZ/T 210.4-2008《职业卫生标准制定指南 第4部分:工作场所空气中化学物质测定方法》的要求,能准确地测定工作场所空气中磷酸三丁酯含量.
