T/NAIA 0161-2022 Determination of Chemical Oxygen Demand in Coal Mine Water with High Chloride Content using Silver Salt Precipitation-Reaction with Reactive Red Method
Abstract
Main technical content: This document specifies the silver salt precipitation- dichromate method for determining the chemical oxygen demand in high-chlorine mine water. This document is applicable to the determination of chemical oxygen demand in high-chlorine mine water in coal mines. The chloride ion content range is 1000-7000 mg/L. When the chloride ion content exceeds this limit, the determination can be diluted. When the sampling volume is 10.0 ml, the detection limit of this method is 4 mg/L, and the determination limit is 16 mg/L.
