有机氯农药（Ops）严重干扰多氯联苯（PCBs）的测定，本文采用微波加热技术将Ops碱解，在优化的实验条件下能完全消除六六六（HCH）、双对氯苯基三氯乙烷（DDT）、二氯二苯二氯乙烷（DDD）的干扰，二氯二苯二氯乙烯（DDE）、艾试剂（Aldrin）、狄试剂（Dieldrin）也有一定数量的减少，狄试剂经浓硫酸处理后其干扰完全消除。通过对合成土壤样品的处理，表明该法能有效地碱解Ops，消除其对测定PCBs的干扰；并能在碱解Ops的同时萃取PCBs，PCBS回收率为84．1％，相对标准偏差为2．7％。本方法快速、高效，减少了有机溶剂的使用量。
Organochlorine pesticides (Ops) seriously interfere with the determination of polychlorinated biphenyls (PCBs). In this paper, microwave heating technology was used to alkalize Ops and completely eliminate hexachlorohexahydrate (HCH), bis-p- There is also a certain amount of decrease in the interference of DDT, DDD, DDE, Dilrin, Dieldrin, Reagents by the concentrated sulfuric acid after its interference completely eliminated. The results showed that this method can effectively hydrolyze Ops and eliminate its interference with the determination of PCBs. PCBs can be extracted simultaneously with alkali hydrolysis of Ops, the recovery rate of PCBS is 84.1%, and the relative standard deviation is 2.7%. The method is fast and efficient, reducing the use of organic solvents.
