CODMn online automatic monitoring instrument and water quality online analyzerTechnical Specifications

　　The permanganate index is a commonly used indicator to reflect the pollution of organic and inorganic oxidizable substances in water bodies. It is defined as the equivalent amount of oxygen calculated from the consumption of certain organic and inorganic reducing substances in an oxidized water sample under certain conditions. The index cannot be used as an indicator of theoretical oxygen demand or total organic matter content, because under specified conditions, many organic matter can only be partially oxidized, and volatile organic matter is not included in the measured values. The chemical oxygen demand measured using a solution as an oxidant, formerly known as manganese method chemical oxygen demand. In China's new environmental water quality standards, the value has been renamed as permanganate index, and only the value measured by the acidic method is referred to as chemical oxygen demand. The International Organization for Standardization (ISO) recommended method is limited to the determination of surface water, drinking water, and domestic sewage, and is not applicable to industrial wastewater.

　　CODMn Online Automatic Monitoring Instrument

　　1、 Principle

　　Add a known amount of sum to the sample, heat it at high temperature for a certain period of time, and remove the sample

　　Some organic and inorganic reducing substances in the product are oxidized, and excess sodium oxalate is added after the reaction to reduce the residue

　　Yu, drip excess sodium oxalate back into the standard solution and calculate the sample

　　Medium potassium permanganate index value
