BF-108B COD analyzer
Detection principle:
Using a sealed digestion tube, a special oxidant containing a certain amount of potassium dichromate is used to dissolve the water sample in a strong acidic solution at a constant temperature of 165 ℃ under the action of a catalyst, so that the reducing substances in the water are oxidized. The total absorbance of the unreduced Cr6+and reduced Cr3+in the water is measured at different wavelengths, or the absorbance of the reduced Cr3+is measured. After system processing, the C content (mg/L) is directly displayed.
Scope of application:
It can be widely used in colleges and universities, research institutes, sewage treatment plants, environmental monitoring stations, electroplating, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, dairy industry, electronics, municipal engineering and other industries.
