摘　　要：比较氧弹瓶燃烧和管式炉燃烧裂解两种方法对PCP的氧化裂解效果，得出氧弹瓶燃烧法回收率高于管式炉燃烧裂解法：随后采用氧弹瓶燃烧-离子色谱法对PCP进行检测，得出在样品加标浓度为50～1000μg/L时，样品的回收率为71％-108％。不同加标浓度的重复性和重现性试验表明，方法的相对标准偏差RSD为3．92％～13．94％，证明该方法具有可靠性。对纺织品中的五氯苯和四氯邻二甲苯用同样方法进行检测，在加标浓度为100～1000μg/L时，样品的回收率为82％-102％，说明氧化裂解-离子色谱检测方法适用于不同的有机氯化合物．具有普遍适用性。Compared with tube furnace combustion pyrolysis method, the oxygen bomb combustion method has higher recovery rate which is more appropriate to degrade organochlorine compounds. Accordingly oxygen bomb combustion-ion chromatography is chosen to determine the content of PCP in textiles. The results show that within the concentration range of 50-1 000 μg/L, the recovery rate of spiked substance is between 71% and 108%. Under different spiked substance＇ concentration, the relative standard deviation is between 3.92%-13.94%, which suggests that this method is reliable. Oxygen bomb combustion-ion chromatography is used to determine the content of pen- taehlorophenyl and tetrachloro-o-xylene. Within the concentration range of 100-1 000 μg/L, the recovery rate of spiked substance is between 82% and 102%, which is suitable for various organochlorine compounds.
