Organic chelating agent

Organic chelating agents are organic compounds with chelating properties that can form stable complexes with metal ions. These organic chelating agents can be used in fields such as water treatment, metal extraction, bioanalysis, and medicine.

Common organic chelating agents include:

EDTA (ethylene diamine tetraacetic acid): EDTA is an organic chelating agent widely used in water treatment and pharmaceutical fields, which can form stable complexes with various metal ions.

DTPA (diisopropylamine tetraacetic acid): DTPA is also a commonly used organic chelating agent, forming stable complexes with many metal ions, especially iron, copper, and manganese.

NTA (n-alkyl triethylenetetramine): NTA is a biodegradable organic chelating agent commonly used in environmental monitoring, such as the measurement of heavy metals in oceans and soil.

CDTA (Cyclohexanediamine Tetraacetic Acid): CDTA is a low toxicity organic chelating agent that can form complexes with metal ions such as cadmium, copper, lead, and zinc.

HEDTA (ethylenediamine hexaacetic acid): HEDTA is a powerful organic chelating agent that can form more stable complexes and dissolve certain metal oxides and carbonates.

These organic chelating agents HEDP all have certain selectivity, that is, they have different affinity and selectivity for different metal ions. Therefore, appropriate organic chelating agents should be selected according to actual needs during use, and their dosage and concentration should be controlled to avoid adverse effects on the environment and human body.
