What is the chelation capacity of HEDP for cations like calcium and magnesium?

Posted on By admin No Comments on What is the chelation capacity of HEDP for cations like calcium and magnesium?

This is an excellent question that gets to the heart of how HEDP functions. The chelation capacity of HEDP for cations like calcium and magnesium is very high, but it’s crucial to understand that this is not its primary function in water treatment. Its main role is threshold inhibition (crystal distortion), not stoichiometric chelation. Here’s a detailed breakdown:…
