Bio-Fenton Process for Advanced Treatment of Refractory Compounds
Continuous treatments of chlorinated compounds such as 2,4-Dichlorophenol (2,4-DCP) and Pentachlorophenol (PCP)were conducted using different aquatic plants.Experimental results showed that efficient treatment was achieved for 2A-DCP but not for PCP.Enzymatic assays indicated that primal enzymes involved in 2,4-DCP removal were peroxidises (POs) that catalyze the following reaction; 2,4-DCP + H2O2 → Products + a2O.Endogenous n2O2 levels in plants were in the range of 0.1 to lmmol/kg-F.W.Based on this relatively high H2O2 levels,experimental trials were conducted to decompose PCP by adding Fe2+ ions,demonstrating that PCP could be removed quickly in parallel with the decrease in H2O2 concentration and the production of chloride.ions.In addition,OH radical formation was detected by Electron Spin Resonance (ESR) Analysis.These results demonstrate the occurrence of a biological Fenton reaction (i.e.Bio-Fenton Process),which may be used for further treatments of other refractory pollutants.
