Chemicals are chemicals that can form a stable collateral with metal ions. They are combined with the coordination keys to a metal ion to form complexes with chemical stability. The following are the main functions and uses of chelating agents:
Metal ions Removal: Chelators can react with metal ions in the water, so that metal ions can form stable complexes, thereby preventing the precipitation and deposition of metal ions. This plays an important role in preventing metal corrosion and scale in pipelines, equipment and industrial systems.
Water purification: Chelators can be used for water quality purification during water treatment. They can combine with heavy metal ions (such as lead, mercury, cadmium) in the water to form insoluble or insoluble complexes to effectively remove heavy metal pollutants in water.
Pharmaceutical industry: Chelators are commonly used in the pharmaceutical industry to stabilize metal ions in drug molecules. A complex with metal ions can extend the stability of the drug and maintain the activity of the drug.
Chemical analysis: Chemistry agents are widely used in chemical analysis. They can react with metal ions, so that metal ions have better chemical stability and measurement, which is convenient for quantitative analysis and detection.
Transportation and storage of metal ions: Chelators can be used in the transportation and storage of metal ions. A complex with metal ions can increase the stability and solubility of metal ions to facilitate transportation and storage.
It should be noted that the selection of chelating agents should be carried out according to the characteristics of the complex and metal ions required. Different chelars are suitable for different metal ions, and the concentration and usage method of chelating agents need to be determined according to the actual situation and requirements. In addition, the use of chelating agents should follow relevant safety operating procedures and regulations to ensure the safety of personnel and environment.
