Abstract

In this research, we demonstrated the effectiveness of potassium polyethylene plycolate method (KPEG) in the removal of polychlorinated biphenyls (PCBs) from transformer oil. A commercially available transformer oil composed of a mixture of PCBs (Aroclor 1254) was treated by polyethylene glycol 400 (PEG 400), with potassium hydroxide (KOH). The relative efficiency of the different treatments was assessed in terms of the destruction and removal efficiency (DRE, %) by means of gas chromatography at different reaction times. Our results revealed that the DRE average, with a value of 95.0%, was obtained under the experimental conditions: mol ratio KOH/PEG = 2:1 and KPEG/oil = 30:1 for 3 h 30 min of reaction at 90°C. Additionally, the influence of time demonstrated effect on the dechlorination of PCBs.

变压器油中多氯联苯处理分析

在这项研究中，我们证明了聚乳酸钾法(KPEG)去除变压器油中多氯联苯(pcb)的有效性。用聚乙二醇400 (PEG 400)和氢氧化钾(KOH)处理由多氯联苯混合物(Aroclor 1254)组成的市售变压器油。通过气相色谱法测定不同处理在不同反应时间下的破坏和去除效率(DRE， %)，评价不同处理的相对效率。结果表明，在KOH/PEG = 2:1, KPEG/oil = 30:1的条件下，在90℃下反应3 h 30 min, DRE平均值为95.0%。此外，时间对多氯联苯的脱氯也有影响。
