摘　　要：指出了近年来,药物及个人护理用品(PPCPs)被大量使用,已经对动植物和人类造成了很大的影响。吉非罗齐(GEM)是在世界上广泛使用的抗血脂类药物,在污水处理厂中经常频繁检出。而传统的污水处理厂对GEM的去除效率较低,因而需要发展更有效的去除水中类似药物的技术。采用了一种新型的高级氧化技术-介质阻挡放电(DBD)等离子体来降解水中的GEM,并利用高效液相色谱(HPLC)检测了样品中残留的GEM的浓度,考察了放电时间和放电功率等对降解效率的影响。结果表明:DBD可以有效地降解水中的GEM,并随着放电时间和放电功率的增加降解效率也逐渐增加。Inrecentyears,pharmaceuticals and personal care products（PPCPs）have been widely used around the word,which poses serious effect to animals and humans.Gemfibrozil（GEM）is widely used to treat coronary disease and have been frequently detected in wastewater treatment plants（WWTPs）.GEM is durable and intractable by WWTPs.Hence,it is essential to develop effective techniques to remove GEM in aqueous.Dielectric Barrier Discharge plasma is one kind of advanced oxidation techniques（AOPs）which is frequently applied to degrade organic pollutants in water.High performance liquid chromatography（HPLC）is applied to detected the concentration of GEM in samples.The effect of discharge time and discharge power on the degradation rate are determined and the degradation rate is increased with the increasing discharge time and discharge power.
