1、 Product Overview
Copper is an essential trace element for the human body, with an estimated daily requirement of 20mg for adults. When copper in water reaches 0.01mg/L, it has a significant inhibitory effect on water self purification. Copper is highly toxic to aquatic organisms. Some people believe that the initial toxicity concentration of copper to fish is 0.002mg/L, but it is generally considered safe for fish to have a copper content of 0.01mg/L in water. The toxicity of copper to aquatic organisms is related to its form in water, and the toxicity of free copper ions is much greater than that of complexed copper. The main sources of copper pollution are wastewater discharged by enterprises in electroplating, metallurgy, hardware, petrochemicals, and chemical industries.
This analytical instrument is capable of long-term unmanned automatic continuous operation according to on-site settings, and is widely applicable to industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of the on-site testing conditions, corresponding preprocessing systems can be selected to ensure the reliability of the testing process, accurate testing results, and fully meet the on-site requirements of different occasions.
