摘要
目的建立工作场所空气中正丁基缩水甘油醚的溶剂解吸气相色谱测定方法。方法按照《工作场所空气中有毒物质检测方法研究规范》的要求进行实验。结果本方法在0～500μg／ml范围呈线性关系；样品在4℃冰箱下于炭管中可保存10d；方法的重现性好，不同浓度的相对标准偏差为0．86％～2．58％；方法的最低检出限为2．0μg／ｍl；平均解吸效率为95．41％～99．15％；采样效率为98．05％～100％；100mg活性炭对正丁基缩水甘油醚的穿透容量是5．4ｍg；空气中与正丁基缩水甘油醚共存的二苯醚等在夺方法条件下不干扰测定。结论此方法各项指标均达到《工作场所空气中有毒物质检测方法研究规范》的要求，适用于工作场所空气中正丁基缩水甘油醚的现场监测。
Objective To establish solvent desorption gas chromatographic method for determination of air n-butyl glycidyl ether in workplace. Method This method is based on ＂Standardization of methods for determination of toxic substances in workplace air＂ . Result ＂This method presents linear relation within 0-500μg/ml. The sample could be. stored in the activated carbon tube at least for 10 days. Precision （RSD）： 0.86%-2.58%. Detection limit： 2.0 μg/ml. Desorption efficiencies were 95.41%-99.15%. Absorption efficiencies were 98.05%-100% ,The breakthrough volume of 100mg of activated carbon was 5.4mg. In this determination, authors found without interferences from other volatile organic solvents, e.g., diphenyl oxide.Conclusion This method-might meet the requirement of ＂Standardization of methods for determination of toxic substances in workplace air＂. It is feasible for determination of n-butyl glycidyl ether in workplace air.
