Nanocolor COD 160
COD Hg free
Photometric determination of COD without use of mercury saltsPhotometric determination of decrease in chromate concentration after two hours and oxidation with potassium dichromate / sulphuric acid/silver sulphate at 148 °C without use of toxic mercury salts.
Chloride contents below 2000 mg/l are eliminated by a simple filtration pretreatment step using a special cartridge and do not interfere.The chemical oxygen demand of a water sample is determined by silver-catalysed oxidation with potassium dichromate/sulphuric acid at 148 °C during a two hour period. |
