摘　　要：纺织品中五氯苯酚含量测定有两种国标方法,即GB/T18414.1—2006和GB/T18414.2—2006,前者采用气相色谱-质谱法,后者则采用气相色谱法。通过分析两者在测试方法与原理、样品提取方法,以及仪器分析方面的差异,结果表明,GB/T18414.2—2006的样品提取方法适用性更强,测定低浓度五氯苯酚含量时的结果更为可靠;而GB/T18414.1—2006对五氯苯酚的定性更为方便准确。实际检测工作中,可将两者结合使用。Two methods of GB/T 18414.1--2006 and GB/T 18414.2--2006 of testing of pentachlorophenol （PCP） in textiles were introduced and compared, such as principle, sample treatment, and instrumental analysis. The results showed that GB/ T 18414.2--2006 afforded more applicable way for sample treatment and was more reliable for lower concentration of PCP while qualitative analysis of GB/T 18414.1--2006 was more convenient and accurate. In actual work, a combination of both methods can be used.
