T9000CODcr Tayada Biyaha ee Tooska ah ee khadka tooska ah
Mabaadi'da Alaabta
Muunadaha biyaha, xalka dheef-shiid kiimikaadka potassium dichromate, xal sulfate qalin ah (silver sulfate sida kicinta ayaa lagu dari karaa si ay u oxidize xeryahooda aliphatic toosan si wax ku ool ah) iyo isku dhafka sulfuric acid ee la isku daray ayaa lagu kululeeyay 175 ℃. Midabka xeryahooda dabiiciga ah ee xalka oksaydhka dichromate ion wuu beddeli doonaa. Falanqeeyaha ayaa ogaanaya isbeddelka midabka oo u beddela isbeddelka qiimaha COD ka dibna soo saara qiimaha. Qadarka dichromate ion ee la isticmaalo waxay u dhigantaa qadarka walxaha organic oxidizable, oo ah COD.
