Cr6+ Online Analyzer, Cr6+ Online Meter, Water Analyzer, Sewage Water Treatment, Waste Water Treatment
The toxicity of Cr is related to its existence valence. Generally, the toxicity of the Cr6+ is 100 times higher than the toxicity of the Cr3+. The Cr6+ is easier for the body to absorb and accumulate in the body, leading to liver cancer. So, Cr6+ is one of the indicators for the implementation of total quantity control.
This monitoring device can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.
The product is determined by diphenylcarbonyl dihydrazine spectrocolorimetric method. After mixing the water sample with regulator, under the acidic environment and with the presence of indicator, the hexavalent chromium reacts with indicator to form a kind of colored complex. Then, the analyzer is used to detect the change in color and convert the change into a hexavalent chromium value for outputting. The amount of generated colored complex is equivalent to that of hexavalent chromium.
