EDTA is resistant to hydrolysis.
Photolytic degradation is practically only
relevant for the Fe(III)EDTA complex and has been shown in surface
waters. It is depending on pH and irradiation; in summer
photodegradation rates will be higher and mainly when pH is <= 7.
Further abiotic degradation processes as
reaction with OH-radicals or single oxygen have (compared to the direct
photolysis) very low reaction constants and are of no environmental
