This paper assesses the potential of mechanochemical method with fine metal powder, glycol and alkali for polychlorinated biphenyls (PCBs) removal from waste insulating oil. The effects of relevant parameters, such as kinds of chemicals, rate and time of milling were examined. After each run, the total PCBs content in waste insulating oil was measured. Polyethylene glycol 200, long chain-glycol was more effective than triethylene glycol and ethylene glycol, short chain-glycol as hydrogen donor in mechanochemical dechlorination of PCBs. A maximum of 99.9% PCBs removal (below 2 ppm) and 94% total chlorine removal were achieved with the mechanochemical process for 2 h.
本文评估了使用细金属粉末、二醇和碱的机械化学方法从废绝缘油中去除多氯联苯（PCBs）的潜力。研究了相关参数的影响，如化学物质的种类、研磨速率和时间。每次实验后，测量废绝缘油中多氯联苯的总含量。聚乙二醇200（长链二醇）在多氯联苯的机械化学脱氯中作为氢供体比三甘醇和乙二醇（短链二醇）更有效。通过机械化学过程处理2小时，多氯联苯的去除率最高可达99.9%（低于2 ppm），总氯去除率为94%。
