UV‐Activated Persulfate Oxidation of Orange III Dye Using KrCl Excilamp
The paper demonstrates the possibility of using UV radiation of KrCl excilamps to activate persulfate (PS) in advanced oxidation processes. The model compound—the dye Orange III—is subjected to treatments involving UV radiation, persulfate, and/or ferrous ion, alone or in combinations. According to Orange III oxidation efficiency, the tested oxidative systems can be arranged in the following order: PS/UVex/Fe2+ > PS/UVex > PS/Fe2+ > UVex > PS. Furthermore, the energy efficiencies of the oxidative systems enhanced by UV radiation from a KrCl excilamp (222 nm) and a low‐pressure mercury lamp (254 nm) are compared. The highest energy efficiency and mineralization are achieved by activating persulfate with a combination of a transition metal (Fe2+) and UV radiation of a KrCl excilamp.
