摘要
在水和废水中苯胺的现行测定方法 ̄[1]基础上,以0.05mol/LH_2SO_4代替固体硫酸氢钾进行酸度调节,并通过标准样品及实际样品的分析,试验了改进的方法。此种改进简化了分析程序,提高了分析效率。在大量实验基础上,建立空白试验、准确度质量控制图,以期对定期例行监测及大批调查分析提供可行的质量保证措施。
On the basis of the present determination of aniline in water and wastewater,0.5 mol/L H_2SO_4 instead of soiid KHSO_4 was used to eontrol acidity in this paper。The improved method was tested with standard samole and actural sample. This improvement simplifies the analytical progratm and promotes analy-tical efficiency.Based on a large of experimenst,the quality control map of-blank test and accuracy were set up to provide the measures of quality control for routine monitoring and large numbers of investigation analysis of aniline。
