| 中文摘要: |
| 采用离子交换树脂XAD-7吸附-毛细管柱气相色谱法测定工作场所空气中乙二醇，结果表明，该方法在0 mg/L～1 116 mg/L范围内线性良好，方法检出限为0.88 mg/L，当采样体积为7.5 L时，最低检出质量浓度为0.11 mg/m3。乙二醇标准溶液测定结果的RSD为1.3%，空白加标回收率为80.1%～107%，方法的采集效率为98.0%。 |
| 英文摘要: |
| The method of determining ethylene glycol in the air of workplace was established by ion exchange resin XAD 7 adsorption capillary column gas chromatography. Experimental results showed good linear relationship in the range of 0 mg/L～1 116 mg/L and the lowest detection limit was 0.88 mg/L. The minimum detectable concentration was 0.11 mg/m3 when the sampling volume was 7.5 L. The relative standard deviation（RSD） of standard solution of ethylene glycol was 1.3%. The blank standard addition recoreries were between 80.1%and 107%, the collection efficiency was 98.0%. |
