包钢固定污染源中氮氧化物测试方法的探讨

Discussion on Nitrogen Oxides Determining Methods in Fixed Pollution Source of Baotou Steel

为了找出适合包钢实际情况的固定污染源中氮氧化物测试方法,对定电位电解法和盐酸萘乙二胺分光光度法进行了对比试验。从测试数据统计分析得出2种测试方法测得结果无显著性差异,可以用定电位电解法测定氮氧化物。

In order to find the appropriate nitrogen oxides determining methods of the fixed pollution source in Baotou Steel, the competitive test of the fixed potential electrolysis method and N（ 1 - naphtyl ） - ethylenediamine dihydrochloride speetrophotometrie method is made. The statistical data from tests shows that the results of two testing methods have no significant difference, the fixed potential electrolysis method can be used for determining the content of nitrogen oxides.
