中文摘要:
      使用美国LecoCS-3碳硫测定仪以W-Fe为助熔剂测定大气粉尘中碳硫含量.考察了空白值、助熔剂、分析时间对碳硫释放的影响,并应用mcrosoft Excel 2000软件处理试验数据,最终得到粉尘样品中碳硫含量.方法快速准确,测定范围为0.1%~3%,相对标准偏差优于7%.
英文摘要:
      Tungsten and iron chip as flux the carbon and sulfur in suspended particulates can be successfully determined at the same time by the HF-combustion IR absorption spectrometric method. The influence of black value and flux and analysis time is examined. Virtue of this method is rapid and accurately. Carbon and sulfur in range of 0.1%~3% can be determined accurately. The relative standard deviation is less than 7%.
