Controlled release of iron for activation of persulfate to oxidize orange G using iron anode
Persulfate (PS) can be activated by transition metal to generate a sulfate radical and oxidize persistent organic pollutants. However, activation with excessive Fe(II) causes unnecessary self-degradation of PS. In this study, Fe(II) was slowly and continuously injected electrochemically using an iron anode to minimize the self-degradation of PS. Additionally, reaction rate was controlled by adjusting the current intensity applied to the system. Total organic carbon (TOC) was analyzed as an indicator of complete mineralization because the model pollutant, orange G (OG), produced secondary pollutants after disruption of the azo bonds. The removal rate of TOC was 1/10-th of that for OG. In addition, the effect of molar ratio of OG and PS was also studied to confirm the complete mineralization of OG.
