Chelators are a type of chemicals that have chelated effects, also known as the container. They form a stable complex with metal ions to change the nature and behavior of metal ions. The following is the role and common use of chelating agents:
The stability of metal ions: chelating agent can form complexes with metal ions, surrounds metal ions in its molecules, and stabilize metal ions through the control key. This can prevent metal ions from precipitation, oxidation or other reactions, and improve the stability of metal ions.
The dissolution and extraction of metal ions: Some chelated agents have good solubility and can be extracted from the original insoluble or insoluble compounds. This is very useful for separation and purified metal ions.
Selective adsorption of metal ions: Different chelated agents have different selective adsorption capacity for metal ions. By selecting the appropriate chelating agent, you can selectively adsorb a specific metal ions, so as to enrich, separate and detect metal ions.
Catalytic effects of metal ions: Comparative complications formed by some chelated agents and metal ions have catalytic activity, which can play a catalyst in chemical reactions. This is of great significance for some organic synthesis and industrial catalytic processes.
Drugs and poisoning: Chelators can be used to treat metal poisoning or related diseases. They can form a stable complex with toxic metal ions to reduce their toxicity to the human body.
Food and drinking water treatment: Chelators can be used in food processing and drinking water treatment, remove or stabilize metal pollutants, and improve the quality and safety of the product.
It should be noted that the selection of chelating agents should be determined according to the characteristics and target application of the required parts. When using chelating agents, we should follow related guidelines and regulations, and pay attention to the potential impact of environmental and human health.
