Commercially, the most important property of a chelant is how well it performs in a chosen application and whether it delivers cost-effective performance for the end user. In the early days of biodegradable chelating agents, much attention was devoted...

It is more difficult to decide whether chelation plays any part in the activity of salicylic acid which is released in the biodegradation of aspirin and, especially in cases of abuse of this drug and in the therapy of rheumatic disease, may be present in appreciable quantities in the body.

Although there are reports of improved biodegradation with Fenton pretreatment, there are also reports indicating limitations of Fenton pretreatment. Acid conditions often used for Fenton treatment are usually incompatible with microbial activity, and measures to overcome this incompatibility must be taken. For example, the use of iron chelators and higher pFi values is one approach that has been taken [61].

Stable complexes with EDTA and its related compounds are formed with most polyvalent metal ions, hence their wide use in chelation therapy. Pure EDTA is a white crystalline solid with a relative molar mass of 292.1. It is a weak, tetrabasic acid which is sparingly soluble in water. EDTA is not metabolized in the human body and is effectively non-biodegradable in the environment.
