Application of Ultrasonic Wave on Platinum Group Metals Recovery from Zirconia Oxygen Sensor
-
摘要: 主要介绍了利用超声波回收氧化锆氧传感器中铂族贵金属的方法。此方法具有简单高效,无毒无害的特点。铂族贵金属在氧化锆氧传感器中作为活性电极被大量应用,由于铂族贵金属资源稀缺和价格昂贵,从废弃的氧化锆氧传感器元件中回收铂族贵金属在经济和环保方面具有十分重要的意义。Abstract: This paper gives a method for platinum group metals recovery from zirconia oxygen sensor by ultrasonic wave which is simple,efficient,non-toxic and environmentally friendly. Platinum group metals as active electrode are widely used in zirconia oxygen sensor. As resource scarcity and high price of platinum group metals,recovery of platinum group metals from the waste zirconia oxygen sensor has great significance in terms of economic and environmental.
