There are many strategies for measuring COD, Just about every with its benefits and drawbacks. The most typical solutions include things like the dichromate system, the permanganate method, as well as closed reflux approach.The permanganate system is comparable but utilizes potassium permanganate as opposed to potassium dichromate. The shut reflux

With this technique the chemical oxygen demand is set through chromic acid digestion of organic and natural masses in wastewater. Based on this technique the COD turned a normally utilized sum parameter in wastewater analysis. It is actually used for preparing of wastewater remedy crops, for controlling the cleaning efficiency and for that cal
