Characteristics of Fe2+/H2O2/UV Oxidization Process

摘要: The characteristics of a Fe2+/H2O2/UV system, which was constructed by introducing UV irradiation (wave length 253.7 nm) into Fenton oxidization were evaluated on decomposition pyridine and other organics. effect oxygen organic also examined feeding air the reactor. optimum Fe2+ concentrations for acetic acid found to be 45.6 9.1 mg l−1, respectively, under conditions 250 mgTOC 2450 mgH2O2 35°C. On hand, there existed no H2O2 concentration in range 550 l−1 l−1. Aeration an effective method increase TOC removal efficiency. reaction rate increased increasing temperature. Of 15 compounds investigated this study, organics with high electron density, such as aromatic heterocyclic relatively easy decompose, compared aliphatic alcohols, ketones, or...
