19/9/2018 · Answer. COD2 Vials are a mercury-free alternative to traditional COD tests. Mercuric sulfate is used in traditional COD vials specifically to treat chloride interference. Because of this, the COD2 reagents are susceptible to chloride interference at all levels. For more information please see the article titled, Does Hach have any literature on
Recent advances in oxygen demand research haveexpanded the number of options available for testing. The purpose of this technical bluebook is to 1) provide background information on oxygen demand testing, and 2) discuss the comparative advantages of methods cur- rently available, including the new Hach Manganese III COD Method designed to eliminate hazardous heavy metals waste.
