摘  要：
使用吹扫捕集(P&T)-微氩离子检测器(MAID)-气相色谱法(GC)(P&T-MAID-GC)测定水中18种挥发性有机物(VOCs),如二氯甲烷、顺、反式二氯乙烯、三氯甲烷、甲苯、氯苯和乙苯等,实现了进样、吹扫、检测连续进行,无需更换检测器,方法准确性高、重复性好。测定浓度为10μg·L~(-1)的混合标准样品,相对标准偏差均小于10%,范围为1.064%～8.302%;当加标量在5.0μg·L~(-1)和10.0μg·L~(-1)时,空白加标回收率范围分别为85.7%～110.1%和89.2%～100.8%。对比测试结果表明:P&T-MAID-GC法测定18种挥发性有机物的相对误差范围为-9.86%～3.46%,相对标准偏差为0.61%～5.19%;同时更换不同的检测器,其相对误差范围为-9.84%～7.36%,相对标准偏差范围为1.10%～7.88%。两种方法测定的相对误差及相对标准偏差均在10%以内,无明显差异。

摘  要：
Purge-and-trap-gas(P & T)-micro-argon ion detector(MAID)-gas chromatography(GC)(P &T-MAID-GC)was used to detect 18 kinds of volatile organic compounds(VOCs) including dichloromethane, cis-, trans-dichloroethylene, chloroform,toluene, chlorobenzene and ethylbenzene in water, and the injection, purging and testing were carried out continuously without the need to replace the detector, with high accuracy and good repeatability. The relative standard deviations(RSDs)were found to be less than 10% with the range from 1.064% to 8.302% at a mixed standard sample of 10 μg·L~(-1), and the spiked recoveries was ranged from 85.7% to 110.1% at the spiked quantity of 5.0, and 89.2% to 100.8% at the spiked quantity of 10.0 μg·L~(-1). The comparison test showed that the relative errors of 18 volatile organic compound contents detected by P&T-MAID-GC were varied from-9.86% to 3.46%, and the relative standard deviations from 0.61% to 5.19%, simultaneously. While replacing different detectors simultaneously, the relative error was ranged from-9.84% to 7.36% and the relative standard deviation from 1.10% to 7.88% by purification and trapping-gas chromatography. The relative error and relative standard deviation of the two methods were both within 10%, without significant difference(P > 0.05).
