摘要
用气相色谱 -质谱联用仪 ,采用选择离子的方法对染料中间体2,6_二氯_4_硝基苯胺中的多氯联苯进行分析。检出了五氯联苯、六氯联苯、七氯联苯。并对其中六氯联苯用内标法进行了定量。方法快速、准确。
Polychlorobiphenyls in dye intermediate 2,6 _ dichloro _ 4 _ nitroaniline were analyzed by GC-MS in SIM method. Pentachlorobiphenyl, hexachlorobiphenyl, heptachlorobiphenyl were detected out. Then hexachlorobiphenyl was quantitatively analyzed by internal standard method. The method is rapid and accurate.
