甲醛法测定环境空气中二氧化硫

Formaldehyde Method Used for Determination of Sulfur Dioxide in Ambient air

作为环境空气质量的主要指标之一,二氧化硫是污染指数的重要评价因素,因此其监测数据的质量保证尤为重要。本文着重针对甲醛法测定其吸收液的使用、测定条件的选择和干扰因素的排除等问题提出见解。

As one of the main indicators of environmental air quality, sulfur dioxide pollution index is an important evaluation factor, so the monitoring data of the quality assurance is particularly important. In this paper for the use of formaldehyde method to determine the absorption solution, selection of determination conditions and interference factors of rule out such problems as views are put forward.
