摘　　要：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7．2～720．0μg／ml，相关系数为0．99992，方法检出限为0．86μg／ml，最低检出浓度为0．14mg／m^3（以采样空气样品体积30L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／T210．4—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。Objective To establish a practical method forsampling and detectingtributyl phosphate intheworkplace. Methods The samples were extracted by glass fiber membrane, eluted with ether, separated by gas chromatography, and detected by flame photometric detector. Results There were good linear relationship in the minimum detection concentration was 7.2-720.0 μg/ml, and the correlation coefficient was 0.999 92. The detection limit was 0.86 μg/ml, and the minimum detection concentration was 0.14 mg/m^3 （sample volume was 30 L）. Recovery rates were 99.8%-100.2%. The with-in relative standard deviations were 4.0%-5.4% and the between relative standard deviations were 2.0%-5.5% , and average samplingefficiency was about 99.1%-100.0%. Conclusion This method conforms with the requirements of ＂Standardization of Methods for Determination of Toxic Substance in Workplace＂. Tributyl phosphate in air could be determined accurately using this method.
