| 摘 要： | 紫外分光光度法测定水质COD是利用有机物吸收紫外线的特征来测量水中的有机物浓度。与传统COD监测方法相比,它是一种不用化学试剂、对样品无须加热消解、快速、简洁、无二次污染的绿色监测技术。本文通过研究生活污水和工业废水样品的紫外吸光度与化学需氧量之间的相关性,得出在水质稳定的条件下,可利用测定的紫外吸光度值推算出化学需氧量的结果。

| Abstract: | The determination of COD in water by ultraviolet spectrophotometry is to measure the concentration of organic substance based on the feature that organic substance could absorb ultraviolet.Compared with the tradional monitoring method of COD,it is a quick and simple analytical technique,which has the advantages of no reagent application,no digestion,and no secondary pollution.The correlation between ultraviolet absorbency degree and COD in domestic sewage in industrial wastewater was studied in this paper.The result showed that under certain condition,it could calculate COD value from ultraviolet absorbency degree. |
