Introduction: Permanganate index (CODMn) refers to the amount of water used to treat water samples with potassium permanganate as an oxidant in an acidic or alkaline medium. It is expressed in mg/L of oxygen and is a measure of the organic matter and reduction of surface waters. A comprehensive indicator of the degree of pollution of inorganic minerals is generally applicable to the determination of surface water, drinking water and domestic sewage. The GR-2110 online permanganate index monitor is based on the national standard "Determination of water quality permanganate index (GB 11892-89)", which provides early warning and supervision of water pollution caused by organic matter and reducing inorganic substances. Check and other functions. working principle: The instrument uses acid potassium permanganate oxidation-potentiometric titration to detect permanganate index (CODMn) in water. The test procedure is: through the system control, the water sample is automatically collected; the water sample is heated into the reaction tank, and under the high temperature acidic condition, the potassium permanganate partially oxidizes the reducing substance in the water; then the excess sodium oxalate and the permanganic acid are added. Potassium reaction; then the remaining sodium oxalate is counter-titrated with potassium permanganate, the end point of the titration is determined by ORP, the back titration time is obtained, and the working curve is obtained to obtain the test value. typical application: The online permanganate index analyzer can be used for real-time monitoring of permanganate index (CODMn) in groundwater, surface water, and drinking water. If the chlorine content in the water is greater than 300 mg/L, it should be tested using the alkaline permanganate index method. Characteristics 1. Dynamic determination of the titration end point 2. The sampling amount is accurate 3. Reagent cross-contamination is small 4. Temperature control is stable 5. Support automatic / manual calibration and cleaning 6. Remote control
