Description | Chloride ions in water samples are the main interfering components. When the chloride ion concentration is below 2000mg/L, this prefabricated reagent can be used directly. Otherwise, it needs to be treated by dilution,etc. For high-chlorine reagents, the chlorine resistance is designed to reach 20000mg/L. |
Application | COD pre-packed reagent adopts dichromate method and is used for the determination of chemical oxygen demand in various water bodies such as environmental water, seawater, agricultural irrigation water, municipal sewage, industrial wastewater,etc. |
