摘　　要：通过对实验室加标固体样品和实际固废样品的测定,研究了便携式顶空/气相色谱-质谱法(GCMS)-定量环(Loop环)测定固废中高浓度VOCs的性能及在固废污染事故应急监测和固废属性判定中的应用。结果表明,便携式顶空/GC-MS-Loop环测定实验室加标固废中54种高浓度VOCs的加标回收率、精密度和检出限均符合环境监测分析的要求。实际固废样品的复杂性未对VOCs的测定产生干扰,与实验室吹扫捕集/GC-MS法相比,二者相对偏差小于20%。By determining high concentrations of VOCs in laboratory spiked samples and actual solid waste samples,performance of portable headspace/GC-MS-loop ring was evaluated and its application in emergency monitoring as well as waste identification in solid waste pollution accidents were examined.Results indicated that spiked recovery,precision and detection limit of portable headspace/GC-MS-Loop ring for the examined 54 kinds of VOCs in laboratory spiked samples meet the requirements of environmental emergency monitoring and analysis.The complex nature of the actual solid waste had little interference on the measurement of VOCs.Compared with Purge and Trap/GC-MS,the relative deviation between the measured results was less than 20%.
