DEK-1006 Total Nickel Nickel Ion Online Water Quality Analyzer

(1) Working principle: The DEK-1006 total nickel/nickel ion online water quality analyzer uses ammonium persulfate as an oxidant under slightly acidic conditions (sulfuric acid medium) to oxidize divalent nickel in the water sample to tetravalent nickel. Then, in a strongly alkaline medium (pH value about 12), tetravalent nickel forms a 1:3 orange yellow soluble complex with butanedione oxime, with an absorption peak at 470nm wavelength. The concentration of nickel ions in the water sample is calculated based on the absorbance. Water sample pretreatment: In an acidic medium, the water sample is digested with a strong oxidant at high temperature and high pressure. After cooling, the pH of the water sample is adjusted to neutral with reagents. The water sample that has undergone this pretreatment is measured using the above method to obtain the total nickel.

(2) The DEK-1006 total nickel/nickel ion online water quality analyzer has the following basic functions:

-Can set, proofread, and display time, including year, month, day, hour, and minute;

-It has an alarm function for system abnormalities such as equipment power failure, instrument leakage, and inability to import samples into the reactor, and displays the fault content. At the same time, stop running until the system is restarted;

-After each measurement, the pre-treatment device, instrument pipelines, valves, and other components are automatically cleaned;

-Automatic protection for power and water outages, as well as automatic recovery for incoming and outgoing power;

-Regular cleaning and sampling functions;

-Touchscreen viewing is more intuitive and easier to operate.
