Determination COD in Wastewater Using Spectrophotometry

摘要: 介绍经微回流管封闭回流的废水样冷却后在HACH分光光度计中测定COD值的新方法,试验结果表明,本法即快速又节省试剂,相对标准偏差(n=8)和加标回收率均能满足对废水中COD分析测试的质量控制要求.

Abstract: This paper introduces a new method of determining COD in cooled wastewater using return sealed with micro-return line by HACH Spectrophotometer. Experimental results showed that the method was rapid and saved reagent. The standard deviation (n=8) and the recovery rate met the needs of quality control to determine COD in wastewater.
