Metal ion chelating agents are a class of chemical substances that can form stable complexes with metal ions. They combine with metal ions through coordination bonds to form stable complexes and alter the chemical properties of metal ions. The following are several common metal ion chelating agents:
EDTA (ethylene diamine tetraacetic acid): EDTA is a commonly used multi toothed chelating agent that can form stable complexes with various metal ions, such as iron, calcium, magnesium, etc., and is used in water treatment, food industry, medicine, and other fields.
DTPA (dithiophosphate): DTPA is also a common multi toothed chelating agent that can coordinate with various metal ions, such as iron, copper, zinc, etc. It is widely used in fields such as soil remediation, water treatment, medicine, and cosmetics.
CDTA (cyclohexane tricarboxylic acid): CDTA is a multi toothed chelating agent that can form complexes with metal ions such as calcium, magnesium, and manganese. It is commonly used in products such as detergents, cleaners, and pulp bleach.
NTA (ethylenediamine tetraacetic acid): NTA is a common multi toothed chelating agent that can form complexes with various metal ions, such as iron and copper. It is mainly used in water treatment, detergents, agriculture and other fields.
HEDP (Hydroxyethylphosphonic acid): HEDP is a phosphorus containing chelating agent that can form complexes with metal ions such as calcium, magnesium, and iron. It is widely used in fields such as water treatment, scale inhibitors, and corrosion inhibitors.
These metal ion chelating agents have important applications in industries, pharmaceuticals, the environment, and food. By complexing with metal ions, they can regulate their concentration, stability, and activity, thereby exerting specific functions and effects. When using it, appropriate chelating agents should be selected according to different application needs.
