Abstract

Abstract:

The experiment shows that it is feasible to determinate the chemical oxygen demand(COD) of the water from styrene condensate stripper by Fushun chemical plastic plant. We Compared the rapid determination method by COD tester and assay. These results show that the accuracy and precision of relative standard deviation (RSD) is between 0.0%～5.0% through the calculations of the standard addition recovery rate and the measurements of the standard sample. These results meet the requirements of the water quality monitoring in laboratory. Therefore, the above method can be promoted for application.

摘要： 针对抚顺化工塑料厂苯乙烯装置汽提塔凝水COD的测定,考察比较了COD测定仪快速测定法与滴
定法。结果表明,通过对仪器法加标回收率的测定,应用仪器法测定凝水样中的COD,精密度和准确度的相对标准
偏差在0.0%~5.0%之间,均符合实验室质量控制要求,此法可以推广应用。
