The online automatic total nickel analyzer is an optical method heavy metal online analyzer designed according to 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 wastewater. The measured heavy metal elements include environmental protection. The first and second categories of heavy metal prevention and control projects in the 12th Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution.
The water sample is oxidized by the oxidizing agent ammonium persulfate, and reacts with the indicator to form a colored complex in the presence of an alkaline environment and an indicator (dimethylglyoxime), and the analyzer detects the change of the color and This change is converted to the total nickel value output. The amount of colored complex formed is equivalent to the total amount of nickel.
