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.
