摘要
还原偶氮比色法分析硝基苯,分析结果受锌渣和慢速滤纸吸附系统误差的影响,结果偏低.用苯胺作标准,可去除硝基苯前处理还原中吸附产生的系统误差,提高硝基苯分析结果的可比性、准确性.
The data of nitrobenzene was lower when determination by nitrobenzene-reduction with Zinc-N（1 -Naphthyl） ethylene diamine dihydrochloride spectrophotometric method, because of absorption of zinc sediment and filter paper. In this paper, the system error of the process of reduction and filtration, the accuracy and comparability were improved by standard analysis of aniline.
