摘要
本文介绍了盐酸萘乙二胺分光光度法测定大气中NO2的浓度,本方法的检出限为0.018μg.mL-1,最低检出浓度为0.009mg.m-3,测定范围为0.018～0.7μg.mL-1,相对标准偏差1.3%～3.4%,采样效率为98.4%。
This paper introduced the method of determining the concentration of nitrogen dioxide in the atmosphere using N（1-naphthy1）-ethylenediamine dihydrochloride spectrophotometric method,the detection limit of this method was 0.018μg·mL-1,minimum detectable concentration was 0.009mg·m-3,measurement range was 0.018～0.7μg·mL-1,relative standard deviation was 1.3%～3.4% and sampling efficiency was 98.4%.
