Chemical chemicals that can form a stable collateral with metal ions. Their ingredients can be different due to different applications and needs. Below are the main components of several common chelating agents:
EDTA (ethyleine tetharine): EDTA is a commonly used chemical, its chemical formula is C10H16N2O8. It has the ability of strong chelated metal ions and can form a stable complex with a variety of metal ions such as calcium, magnesium, and iron.
DTPA (diobyl taurine and ethylic acid): DTPA is another common chewing agent, and its chemical formula is C14H23N3O10. It can also effectively form complexity with metal ions, which are widely used in water treatment, medicine and agriculture.
NTA (ethyleine tetharine): NTA is a chelated agent similar to EDTA, the chemical formula is C6H9NO6. It is mainly used in industrial fields such as textiles, printing and dyeing, leather and metal cleaning.
EGTA (ethyleine tetharium ethyleneramnium ethyleine): EGTA is a chemical formula for a specific purpose, and its chemical formula is C14H24N2O10. It is mainly used in the study of biochemistry and cell biology, as a calcium ion chelating agent.
These chelating agents have different characteristics and advantages in different application areas. When used, they need to choose suitable chelating agents according to specific circumstances. In addition, other chelars such as Eddha and Hedta have also been widely used.
