【摘要】：采用離子交換樹脂XAD-7吸附-毛細(xì)管柱氣相色譜法測定工作場所空氣中乙二醇,結(jié)果表明,該方法在0 mg/L~1 116 mg/L范圍內(nèi)線性良好,方法檢出限為0.88 mg/L,當(dāng)采樣體積為7.5 L時,最低檢出質(zhì)量濃度為0.11 mg/m3。乙二醇標(biāo)準(zhǔn)溶液測定結(jié)果的RSD為1.3%,空白加標(biāo)回收率為80.1%~107%,方法的采集效率為98.0%。
[Abstract]:The determination of ethylene glycol in workplace air by ion exchange resin XAD-7 adsorption-capillary gas chromatography shows that the method has a good linearity in the range of 0 mg / L ~ (-1 116) mg / L, and the detection limit is 0.88 mg / L, and when the sampling volume is 7.5 L, the detection limit of the method is 0.88 mg 路L ~ (-1). The lowest detectable mass concentration was 0.11 mg / m ~ (3). The RSD of the determination of ethylene glycol standard solution was 1.3 and the recovery rate of blank standard solution was 80.1 and 107.The collection efficiency of the method was 98.0.
