摘要
本文主要涉及用盐酸副玫瑰苯胺比色法测定大气中的二氧化硫。首先讨论了实验过程中的系统误差控制,然后研究在统计计算中经常遇到的两个问题。实验也说明了用冷却去离子水代替重蒸馏水有相同的效果。
In this paper, the measurement of sulfur dioxide content in atmosphere by colormetric analysis with pararosaniline Ind has been carried out. Firstly, how to reduce the errors in the process of experiment is discussed. Then, two problems commonly occurred in statistical calculation are examined. The results with cool boiled deionized water are shown to be as good as those with redistilled water.
