硝基苯类污染物还原反应分析系统误差的讨论

硝基苯类的物质在测定中，不能因操作过程的复杂，使用的玻璃器皿多，就存在着较大的系统误差，如锌渣吸附和滤纸吸附误差。如果严格按照国家标准方法分析操作，这两种误差几乎没有，否则，工作时绘制的标准曲线斜率不会在规定要求内。因此，《环境研究与监测》和《环境监测管理与技术》刊载的两篇文章存在一些错误。

Error of Analyticl System in Reduction Analysis of Nitrobeuzene Class Pollutents

In the determination of nitrobenzene class, the operation is complicated, the used glass ware is very much, but system error such as zinc dreg absorption and filter paper absorption is not serious. The error almost can not be found by strictly abide the national stardard method, otherwise the slope of standard curre can not meet the require. So some mistake can be found in the two papers which published in the Environmental study and monitoring and the Administration and technique of environmental monitoring.
