title: [Degradation of dimethyl phthalate (DMP) in aqueous solution by UV/Si-FeOOH/H2O2].
abstract: In this study the new catalyst Si-FeOOH was synthesized by adding Si to the traditional FeOOH and the mechanic strength of this new catalyst could be enhanced greatly. The photo-degradation of dimethyl phthalate (DMP) by UV/Si-FeOOH/H2O2 was investigated. The new catalyst Si-FeOOH was amorphous structure with high surface area and low soluble iron by XRD, IR and SEM. The efficiency of DMP degradation by UV/Si-FeOOH/H2O2 could reach 97% after 30 min reaction time at pH 5, 0.5 g/L dosage of Si-FeOOH, and 2.0 mmol/L of H2O2 under 125W UV365 irradiation. DMP could be degraded effectively by synergistic effect of UV, Si-FeOOH and H2O2. The Si-FeOOH photocatalyst can be very easily recovered and its catalytic activity also remained after several rounds of reaction.
