1、 Product Overview:

CODMnIt refers to the mass concentration of oxygen corresponding to the oxidant consumed when using strong oxidants to oxidize organic and inorganic reducing substances in water samples under certain conditions,CODMnIt is also an important indicator reflecting the degree of pollution of water bodies by organic and inorganic reducing substances.

This analyzer is capable of long-term unmanned automatic continuous operation according to on-site settings, and is widely applicable to industrial pollution source discharge wastewater, industrial process wastewater, industrial sewage treatment plant wastewater, municipal sewage treatment plant wastewater, and other occasions. According to the complexity of the on-site testing conditions, corresponding preprocessing systems can be selected to ensure the reliability of the testing process, accurate testing results, and fully meet the on-site requirements of different occasions.

2、 Product principle:

Add a measured amount of potassium permanganate solution and sulfuric acid solution to the sample, mix and digest them. Potassium permanganate oxidizes organic pollutants in the sample, then add a measured amount of sodium oxalate solution to reduce the remaining potassium permanganate, and drip the excess sodium oxalate back with potassium permanganate solution. The titration endpoint is determined by the oxidation-reduction potential, and finally the instrument automatically calculates the permanganate index value.
