CODMn
CODMn, or chemical oxygen demand using permanganate, is a water quality parameter that measures the amount of oxidizable substances in water or wastewater that can be oxidized by potassium permanganate under specified conditions. It is used as a rapid, economical surrogate for the overall organic load and is related to the more widely used CODCr (dichromate COD) test, but it can respond differently to certain compounds.
In typical practice, a sample is acidified and treated with a standardized KMnO4 solution under controlled
CODMn is widely employed in drinking-water treatment and wastewater management for rapid process control, screening, and
Because CODMn and CODCr do not always correlate precisely, CODMn is typically used alongside other indicators
