摘要
五氯酚生产过程中会产生一些剧毒的副产物——多氯二苯并呋喃(PCDFs),应用质谱/质谱(MS/MS)法直接鉴定出国产五氯酚工业品中含有4—8个氯原子的二苯并呋喃类化合物,这可能是我国PCDFs污染的主要来源之一。本方法可用于工业化学品的普查及潜在污染源的调查。
Extremely toxic PCDFs (polychlorinated dibenzofu-rans) can be formed in the production of pentachloro-phenol as by-products. PCDFs including 4-8 chlorine atoms have been identified . in China-made Pentachloro-Phenol using MS/MS method. It is considered as one ofthe main sources of PCDFs contamination in china. This analytical method has been recommended for application in general survey of technical chemicals and investigation of potential pollution sources.
