Low levels of iron enhance UV/H 2 O 2 efficiency at neutral pH

Low levels of iron enhance UV/H 2 O 2 efficiency at neutral pH

While the presence of iron is generally not seen as favorable for UV-based treatment systems due to lamp fouling and decreased UV transmittance, we show that low levels of iron can lead to improvements in the abatement of chemicals in the UV-hydrogen peroxide advanced oxidation process. The oxidatio...

Zusammenfassung:While the presence of iron is generally not seen as favorable for UV-based treatment systems due to lamp fouling and decreased UV transmittance, we show that low levels of iron can lead to improvements in the abatement of chemicals in the UV-hydrogen peroxide advanced oxidation process. The oxidation potential of an iron-assisted UV/H O (UV  + H O  + iron) process was evaluated at neutral pH using iron levels below USEPA secondary drinking water standards (
