Abstract:

Fe₂O₃/H₂O₂, a kind of Fenton-like agent, was used to degrade an anion surfactant, sodium dodecyl benzene sulfonate(SDBS)，in an aqueous solution. Through a number of batch degradation experiments under various conditions, it was found that the reactivity of the system increased by increasing temperature. The SDBS degradation ratio will increase by, respectively, increasing H₂O₂ concentration and Fe₂O₃ dosage at some extent, but too high H₂O₂ concentration or Fe₂O₃ dosage will decrease the degradation efficiency. pH value has some influences on the reactivity of the system; from 2 to 10, the system maintains high efficiencies all the time. It also can be seen that Fe₂O₃/H₂O₂ Fenton-like reaction almost has the same efficiency as homogeneous Fenton reaction, while the former has a widely pH range (2-10), and Fe₂O₃ can be separated easily and has no secondary pollutants.
