Photo-Fenton and Fenton Oxidation of Recalcitrant Industrial Wastewater Using Nanoscale Zero-Valent Iron
Figure 3
Boxplots built up with data from COD and TOC values obtained with dark-Fenton and photo-Fenton treatments. (a) COD reduction (in %) with both treatments; (b) TOC reduction (in %) with both treatments; (c) increase (in %) in the percentage of COD and TOC reduction by photo-Fenton compared to dark-Fenton; (d) changes in COD/TOC ratio due to different treatments.
