Heavy metals and organic matter are one of the most important parameters in water quality analysis. Water is the source of life, so ensuring the quality of water is essential to protect human health. Water quality analysis is a scientific instrument, which is widely used in the fields of environmental protection, food safety and drinking water.
First, let's learn about heavy metal analysis. Heavy metals are a kind of metal elements with high density and toxicity, such as lead, mercury, cadmium, etc. They exist widely in the environment and enter the water body through production and industrial processes, pesticide use, sewage discharge and other ways. The excessive content of heavy metals will pose a serious threat to human health, such as poisoning, nervous system diseases, etc. Therefore, it is very important to accurately analyze the content of heavy metals in water.
Common heavy metal analysis methods in water quality analysis include atomic absorption spectrometry（ AAS）、 Inductively coupled plasma atomic emission spectrometry (ICP-OES) and mass spectrometry. These methods can quickly and accurately determine the content of heavy metals in water samples through the determination and analysis of heavy metals in water samples, and evaluate whether the water quality is up to standard according to the results.
Next, let's discuss organic matter analysis. Organic substances are compounds composed of carbon elements, such as pesticides, drug residues, and organic substances in industrial wastewater. The presence of organic matter will also have a negative impact on water quality, including eutrophication of water bodies and death of aquatic organisms. Therefore, the analysis and monitoring of organic matter in water is also of great significance.
At present, the commonly used organic analysis methods mainly include gas chromatography -Mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), etc. These analytical methods can accurately determine the type and content of organic matter in water samples by separating and identifying the organic matter in water samples. In water quality analysis, organic matter analysis is often related to environmental protection, food safety, medicine and other fields, which is helpful to assess risks and develop corresponding control measures.
In conclusion, heavy metal and organic matter analysis plays an important role in water quality analysis. Through the accurate analysis of the content of heavy metals and organic matter in water samples, we can find and solve water quality problems in time to ensure the health and safety of human beings and the ecological environment.
