环境空气连续监测中SO_2浓度的测定技术探讨

Discussion on the survey technology of SO_2density in the surrounding air continuous monitor

文中通过对环境空气中SO2 浓度连续监测过程中出现的技术难题进行分析探讨 ,对甲醛溶液的配制、SO2标准溶液配制、样品采集与分析及SO2 标准曲线的绘制等几个方面的技术难关采取了相应的措施 。

This paper,according to the analysis and further discussion on the tecnnological difficulties which lying in the course of SO 2 density monitoring in the surrounding air,the corresponding measures are adopted to the compounding to formaldehyde solution,and SO 2 standard solution,sample gather and analysis on the drawing of SO 2 standard curve,and the technological difficulties of other several aspects are introduced.It has obtained better result in the experiment.
