间接碘法测定氮氧化物的氧化度

Determination of Oxidizability of Nitrogenous Oxide by Indirect Iodine Method

在测定工业排放废气中氮氧化物的氧化度时,以间接碘法测定氮氧化物废气中的二氧化氮浓度,同时以中和滴定法测定氮氧化物浓度,从而计算氮氧化物的氧化度。氧化度测定的变异系数为4％以下。

Using indirect iodine method to determine the concentration of NO_2 in flue gas consisting of No_x, and neutralization titration method to determine NO_x simultanuously, then calculated the oxidizability of NO_x.
