Prinsip dɔ:

Potassium permanganate In acidic water bath heating conditions, the reducible inorganic and oxidizable organic matter in water can all be oxidized by potassium permanganate, then by spectrophotometry to measure the absorption of potassium permanganate, after a microcomputer chip calculation directly showing the COD value (mg/L).
