Reductive dechlorination and debromination of halogenated biphenyls (PCBs) and diphenyl ethers (PBDEs) occurs efficiently at moderately elevated temperatures (350-600 °C) with zero valent iron (iron powder) in a nitrogen atmosphere. The proton donors tested were waste transformer oil, iso-octane, and n-decane. Observation of production of biphenyl and diphenyl ether and their condensation products indicates that the reaction is not simple pyrolysis, but a reduction. No halogenated organic products are observed.
在氮气氛围中，用零价铁（铁粉）在中等升高温度（350-600°C）下，可以有效地进行卤代联苯（PCBs）和二苯醚（PBDEs）的还原脱氯和脱溴反应。测试的质子供体是废变压器油、异辛烷和正癸烷。观察到联苯和二苯醚及其缩合产物的生成表明，该反应不是简单的热解，而是还原反应。没有观察到卤代有机产物。
