Abstract
In this work, the photochemical impact of Fe(III)-EDDS complex on the quantum yield of *OH formation and on the degradation of 17 -estradiol (E2) was investigated. The quantum yield of *OH formation by photolysis of Fe(III)-EDDS increased with increasing pH in the range of 3.0-9.0. The effect of Fe(III)-EDDS concentration, irradiation wavelength and oxygen on the quantum yield of *OH formation was also investigated. The degradation of E2 was influenced by the concentration of Fe(III)-EDDS, the solution pH, oxygen and Fe(III) concentrations. This work demonstrates that Fe(III)-EDDS is a photoactive iron species especially at higher pHs and could play an important role in the transformation of organic compounds in the natural environment.
