Abstract

The article aims to highlight one of the highest environmental issues, caused by pollution with persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs). This form of environmental pollution with a negative impact on human health would not be possible without the use of high voltage industrial electrical equipment with dielectric fluids infested with various PCB isomers. In order to carry out the experimental program, samples of dielectric fluids both from Romania and Indonesia were investigated. The PCBs-containing samples were characterized using GC-ECD technique, employing an Agilent 7890 gas chromatograph equipped with a 15 mCi 63Ni µECD detector. PCBs concentrations were calculated using the standard calibration method based on the internal standard according to the corresponding normative documents. Ongoing work is carried out to adapt the technique for the analysis of PCBs in soils contaminated with oil products.

气相色谱分析方法在大容量工业电气设备中油类表征中的应用

这篇文章旨在强调由持久性有机污染物(POPs)如多氯联苯(PCBs)造成的污染所引起的最严重的环境问题之一。如果不使用含有各种多氯联苯异构体的介电流体的高压工业电气设备，就不可能出现这种对人类健康产生负面影响的环境污染。为了实施实验方案，对罗马尼亚和印度尼西亚的介质流体样品进行了研究。采用气相色谱-ECD技术对含pcb样品进行表征，采用安捷伦7890气相色谱仪配15 mCi 63NiµECD检测器。根据相应的规范性文件，采用基于内标的标准校准方法计算多氯联苯浓度。目前正在进行的工作是将该技术用于分析受石油产品污染的土壤中的多氯联苯。
