When it comes to heavy metals, there are many types, many of which are indispensable elements for the human body. Since it is indispensable to the human body, why should we monitor the content of heavy metals in water? It’s not! Only a part of heavy metals are essential elements of the human body (such as: iron, zinc, copper, etc.), we also say that there are many types of heavy metals, not all heavy metals can exist in the human body, in addition, although iron, zinc, copper, etc. are indispensable elements of the human body, but its existence is also appropriate, if less or too much is unfavorable to the body. So on-line monitoring of heavy metals in water is necessary.

Heavy metal water pollution refers to the abnormal concentration of metal elements and their compounds in water with a relative density of more than 4.5, which causes the water quality to decline or deteriorate. Heavy metals with relative densities above 4.5 include copper, lead, zinc, nickel, chromium, cadmium, mercury and non-metallic arsenic.

The Main Ways to Pollute Water are:

1) Mining and beneficiation wastewater, slag, etc. into the water body;

2) Waste water, waste gas and waste residue from smelting industry and ore fuel combustion are discharged into or fall into water bodies;

3) Wastewater and waste residue discharged by electroplating, instrumentation, coating, glass, chemical and other enterprises enter the water body;

4) Surface runoff and farmland drainage carry sediment particles adsorbed with heavy metal elements and their compounds into water bodies.

So what are the instruments for monitoring heavy metals in water?

In fact, this is not a fixed device, and the water quality monitors used for different parameters are also different. Hangzhou Moody Technology is a production of water quality online monitoring equipment manufacturers, heavy metal monitoring instruments in water, such as: tin online analyzer, total manganese online analyzer, nickel online analyzer, antimony online analyzer, chromium online analyzer, total cadmium online analyzer and so on.
