多氯联苯（多氯联苯）的脱氯（PCBs）通过超紫外线（UV）辐射发射了六相位ac辉光放电在先进的六磁场中，其中具有高辐射效率是一种经过调查的实验。Kanechlor KC-300（相当于Aroclor 1242）被用作多氯联苯和异丙基醇具有一个氢供体的功能，被用作溶剂。It is shown that dechlorination reaction proceeds with time under the UV irradiation and almost of PCBs are converted into biphenyl。Sample solutions are contained in a quarts tube with a diameter of 5 cm and a length of 50 cm。多氯联苯的集中比率设定为100 ppm，每个值接近等于，使其被重新包装在转化器的容器中的转化器已填充了多氯联苯绝缘油。Quartz tubes are inserted into a UV light source with a diameter of 10 cm and a length of 50 cm。UV光是由一个six-phase glow discharge at a pressure 0.1 Torr of H2 gas生成的。AC电功率输入到该区域的样本设置约为10 W，对析氯过程的分析是由气体色谱法质量光谱的平均值进行的。（Shimazu GC/MS-QP1100WA） with a column of CBP1-S25 -050（25米·0.33毫米，0.50毫米胶片厚度）。目前研究的目标是开发一个高容量低成本的紫外线光源，哪种方法是适用于确定毒性有机氯化合物的较大数量，如多氯联苯和氯氟碳，通过在先进的多聚磁场中使用聚相ac发光放电产生商业电力系统的频率。自从电荷电流在没有结束失去的情况下就可以真正地流动，没有破裂和等离子体就会变得很好，光线就会不断地流动，而且强度很大。在更远的地方，我们可以用放射性样本几乎一致地从环绕的几何形状和多个电极的位置排列。

Dechlorination of polychlorinated biphenyls (PCBs) by ultraviolet (UV) irradiation emitted from a six-phase ac glow discharge in advanced six poles magnetic field which has a high radiation efficiency is investigated experimentally. Kanechlor KC-300 (equivalent to Aroclor 1242) is used as PCBs and an isopropyl alcohol having a function of a hydrogen donor is adopted as a solvent. It is shown that dechlorination reaction proceeds with time under the UV irradiation and almost of PCBs are converted into biphenyl.Sample solutions are contained in a quarts tube with a diameter of 5cm and a length of 50cm. The concentration ratio of PCB is set to be 100ppm whose value is nearly equal to that of the wasted insulation-oils repacked in containers of transformer which had been filled with PCB insulation-oil. The quartz tubes are inserted into a UV light source with a diameter of 10cm and a length of 50cm. The UV light is generated by a six-phase glow discharge at a pressure 0.1Torr of H2 gas. The ac electric power inputted into the region where samples are set about 10W.The dechlorination process is analyzed by means of gas chromatography mass spectrometry (Shimazu GC/MS-QP1100WA) with a column of CBP1-S25-050 (25m・0.33mm, 0.50mm film-thickness).The purpose of present study is to develop a high capacitive low-cost UV light source, which is applicable to detoxicate a large amount of toxic organic chlorine compounds such as PCBs and chlorofluorocarbons, by using the poly-phase ac glow discharge generated at the frequency of the commercial electric power system in an advanced multi-poles magnetic field. Since the discharge current can flow aontinuously without any breaking and plasma be well confined without end loss, the light is emitted continuously with small fluctuation and efficiently with strong intensity. Furthermore, we can irradiate samples almost uniformly from surroundings by arranging geometrical shapes and positions of multiple electrodes.
