HMA-TMN Total Manganese Heavy Metal Analyzer

-Measurement principle: The instrument is detected by colorimetric spectrophotometry. The sample is first added with digestion reagents, and then pumped to the high-temperature digestion unit for high-temperature digestion. The total manganese in the sample is digested into divalent manganese ions. The divalent manganese ion of the sample reacts with formaldehyde oxime in a slightly alkaline solution and forms a brown colored complex. The spectrophotometric measurement is performed at a wavelength of 470 nm. According to the initial color of the sample and the color change after adding the developer Different degrees to determine the concentration of the analyzed sample. Typical applications: surface water, industrial wastewater (such as electrolytic manganese wastewater), and online monitoring of total manganese at the inlet and outlet of sewage plants
