(1) Working principle:DEK-1008 Total Mercury/Mercury Ion Online Water Quality AnalyzerThe measurement method uses potassium permanganate and potassium persulfate to dissolve the sample at 95 ℃, converting all the mercury contained into divalent mercury. Excess oxidant is reduced using hydroxylamine hydrochloride. Under acidic conditions, mercury ions form orange chelates with dithizone, which are extracted with organic solvents and washed away with alkaline solution.

(2) The DEK-1008 total mercury/mercury 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;
