Posted by Iron ion chelators are a type of chemical reagents widely used in water treatment, environmental protection, chemical analysis, and other fields, mainly used to remove iron ions from water and prevent metal oxidation. Common iron ion chelating agents include the following:
EDTA (Ethylenediaminetetraacetic acid): EDTA is a chelating agent widely used in chemical analysis and water treatment. It can form stable complexes with some metal ions such as iron, calcium, magnesium, etc., thus effectively removing iron ions from water.
DTPA (secondary methylene sulfonic acid Dipropylamine): DTPA is another commonly used iron ion chelating agent, similar to EDTA, which can form stable complexes with some metal ions such as iron, manganese, etc.
EDDHA (4,7-bis (2-hydroxyphenyl) -1,10-phenanthroline-6-carboxylic acid): EDDHA is an efficient iron ion chelating agent with good selectivity and high affinity for iron ions in water.
PBTC (4-phosphosuccinic acid): PBTC is a widely used chelating agent in the field of water treatment, which has good effects in removing iron ions from water and preventing metal oxidation.
In summary, common iron ion chelating agents include EDTA, DTPA, EDDHA, and PBTC, which can effectively remove iron ions from water and prevent metal oxidation, and are widely used.
