摘要
本文采用改进的沙氏曼化学法测定居住区空气中的二氧化氮。本方法的标准曲线斜率值为0.969～1.014 Abs/μg,采样效率为99％,NO_2(气)→NO_2^-(液)转换系数为0.9,各项测定指标与国际标准化组织推荐的方法相一致。
Determination of the concentration of nitrogen dioxide in ambient air of residential areas by modified Griess-Saltzman method. The slops of the calibration curve is 0.969～1.114(Abs/μg),The absorption efficiency is 99％.The test factor of NO_2 (Gas)——NO_2^- (Liquid) is 0.9 All the experiment results in this method consisted with the standard method recommended by ISO. The procedure of the method is simple. The accuracy and precision of the assay are, good.
