摘要
采用Liqui TOCⅡ分析仪分析了城市灰尘样品包括城市街道、居民区、厂区等各功能区地面灰尘总碳含量,探讨了样品研磨颗粒大小等因素的影响。结果表明,采用该法样品前处理方便、简单、分析准确度高、精密度好。
The carbon content in city dust sample of each function area including city street residential area and the factory etc. was analysed by Liqui TOCⅡ instrument, the influence of grain size on the determination was discnssed. The result show that the method is simple on sample preparation, better accuracy and better precision.
