How do you know whether the copper in the water exceeds the standard?

Copper (Cu) is a metallic element. Speaking of metals, in fact, many metal elements are indispensable components of the human body, but if the excess is harmful to the human body! For example: copper. Copper is generally contained in the normal human body, and these coppers are all over the tissues and organs of the whole body. An appropriate amount of copper is crucial to the health of the human body. If the human body lacks copper, it will cause anemia, abnormal hair, abnormal bones and arteries, and cause brain disorders. Excessive amounts can cause liver cirrhosis, diarrhea, vomiting, movement disorders and sensory nerve disorders. We have learned that copper can enter the human body mainly through diet, skin and respiratory system. Therefore, copper that exceeds the standard in drinking water can enter the human body after drinking! In this way, it is very important to know whether the copper in the water exceeds the standard! How do you know that the copper in the water exceeds the standard? In fact, it is very simple, just monitor the copper in the water in real time through the water quality monitor! As for the detection method used, the detection method of different instruments will be different. The total copper online analyzer uses the optical colorimetric method. After the pretreated water sample is injected into the reaction tank by a syringe pump, it first reacts with a strong acid reagent to uniformly oxidize all forms of copper in the water sample into divalent copper ions, and then add a reducing reagent to reduce the divalent copper ions Reduce to cuprous ions, then add masking agent to interfere with the coexisting ions in the water sample, and then add characteristic chromogenic agent for color reaction. Within the measurement range, the degree of color change is proportional to the concentration of copper in water. By measuring the color change The level of copper in the water sample can be calculated. So as to judge whether the copper content in the water exceeds the standard, and deal with it!
