| Abstract: | The photochemical degradation of dimethyl phthalate(DMP) in aqueous solution was investigated via a comparative assessment in vario
us advanced oxidation systems (UV, H2O2, UV/H2O2, UV/Fe2+, Fenton and UV/Fenton). The degradation trends followed the following order: UV/Fenton>UV/H2O2>dark/Fenton>UV/Fe2+>UV>H2O2. It could be inferred from the studies that UV radiation enhanced the removal rate of DMP in the Fenton process and UV/Fenton was the most effective for the decomposition of DMP. According to the experimental result, the concentrations of Fe2+ and H2O2 and pH value were the three main factors that could greatly influence the degradation rate of DMP, and the effect of the factors followed the order: pH value>H2O2 concentration>Fe2+ concentration. The optimum conditions were obtained by orthogonal experiment at initial pH=3-4 for the UV Fenton system, with original Fe2+ and H2O2 concentrations of 3.6×10-4-7.2×10-4 mol/L and 1.9×10-2 mol/L, respectively. |
