disampole tsa metsi, potassium dichromate tshilo ya tharollo, silevera sulfate tharollo (silivera sulfate e le catalyst e ka eketsoa ho oxidize linear aliphatic metsoako ka katleho) le concentrated sulfuric acid motsoako o futhumatsang ho 175 ℃. 'Mala oa metsoako ea manyolo ka har'a tharollo ea oxidation ea dichromate ion e tla fetoha. Analyzer e lemoha phetoho ea 'mala ebe e fetola phetoho ho boleng ba COD ebe e ntša boleng.Palo ea dichromate ion e sebelisitsoeng e lekana le palo ea lintho tse phelang tse oxidizable, e leng COD.
