Chelating agent is a commonly used chemical substance used to form stable complexes with metal ions. The main components and content of chelating agents may vary depending on the specific product. Below are the main components and possible content ranges of some common chelating agents:
Ethylenediaminetetraacetic acid (EDTA): EDTA is a multifunctional chelating agent that forms stable complexes with various metal ions. Its content is usually between 5% and 50% in chelating agent products.
Citric acid: Citric acid can also serve as a chelating agent and can form complexes with certain metal ions. Its content is usually between 1% and 10% in chelating agent products.
Benzoic acid: Benzoic acid is also a common chelating agent component that can form complexes with some metal ions. Its content is usually between 1% and 10% in chelating agent products.
Nitrotrimethylbiguanidine (NTA): NTA is a commonly used chelating agent that can form complexes with certain metal ions. Its content is usually between 1% and 10% in chelating agent products.
It should be noted that different chelating agent products may use different ingredients and contents, which should be determined according to the product manual. In addition, when using chelating agents, it is necessary to follow the correct ratio and usage method to ensure safety and chelating effect.
