摘要
硝基苯类项目分析过程中,经过锌粉还原、过滤等重要环节,能吸附分析组分,引起分析结果偏低,通过理论计算和分析标样对比,找出硝基苯类还原偶氮比色法主要的系统误差。
During the analysis process of nitrobenzene class Pollutants, after reduction and filtration, the analysis component was absorbed, so the determination data was lower. With comparison and analysis, the system error was found out.
