Introduction:
Total Rail Online Automatic Analyzer is an optical heavy metal online analyzer designed to comply with national environmental protection standards. It is applied to the simultaneous online analysis of various heavy metal elements in surface water, industrial process water and industrial waste water. The measured heavy metal elements include environmental protection. Department of "The 12th Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution," and the Type 1 and Type 2 prevention and control of heavy metal projects.
Measurement principle: trivalent iron ions in the water sample are reduced to ferrous ions by hydrogen amine hydrochloride. Under the action of the buffer, ferrous ions react with phenanthroline to form a colored complex, and the analyzer detects the color. Change and convert this change into total iron output. The amount of coloured complexes produced corresponds to the total iron content.
