基于一氧化碳干扰下二氧化硫定电位电解法的方法研究

Study of sulfur dioxide fixed potential electrolysis under carbon monoxide interference

污染源中二氧化硫的测定普遍采用定电位电解法,此法简便、快捷,但结果受干扰素较多,尤其是一氧化碳的影响。针对定电位电解法测定二氧化硫时一氧化碳的干扰进行探讨研究,力求准确的干扰数据,保证检测数据的准确。

The method of fixed potential electrolysis has been widely used in measurement of sulfur dioxide in flue gases.It is fast and convenient,however its accuracies were influenced by various factors,especially carbon monoxide.The interference of carbon monoxide in determination of sulfur dioxide by constant potential electrolysis is research,ensure the accuracy of the test data.
