nature

1. EDTA has a wide range of coordination properties and can form stable chelates with almost all metal ions. Advantages: It provides the possibility of a wide range of determination of elements (better than acid-base and precipitation methods). It is easy to interfere between various components - selectivity 2, the coordination ratio between EDTA and the formed M-EDTA is mostly 1:1 3, and most of the chelates are charged, so they can dissolve in water and react quickly.

It is also used as water purification agent, pH regulator, chelating agent, polyvalent chelating agent and coagulant inhibitor.
