Chemical chemicals that can form a stable collateral with metal ions. They combine with metal ions to form chelated compounds. Chelators have a wide range of applications in many areas. The following are the main functions of chelating agents:
The stability of metal ions: After the chelating agent and metal ions are formed, the metal ions can be in a stable coordinate environment to prevent it from having precipitation, oxidation or other adverse reactions. This helps improve the stability and antioxidant of metal ions.
Enhancement of metal ions: After the chelating agent is equipped with metal ions, the solubility of metal ions in the solution can be increased to make it easier to deal with, transportation and utilization. This is especially important for some metal ions that are difficult to solve in water or other solvents.
Selective separation of metal ions: Because different chelated agents have different control capabilities and selectivity on different metal ions, they can use chelating agents to achieve the selective separation and enrichment of specific metal ions, so as to monitor environmental monitoring, thereby environmental monitoring and environmental monitoring, so as Metal extraction and other fields play an important role.
Chemical analysis and testing: Chemotherapy can form a stable complex with metal ions. These complex can be used in chemical analysis and detection, such as titration titration and spectral analysis. The selectivity of chelating agents allows it to accurately and sensitive detection of specific metal ions.
It should be noted that the use of chelars should be performed under appropriate conditions, and the appropriate chelating agent needs to be selected according to the specific application and needs. In addition, for the chelating agent in the environment and biological systems, it should pay attention to its impact on the ecosystem and potential environmental risks.
