The possibilities of remediation of a Latossolo Vermelho Amarelo artificially contaminated with oil (5,000 mg kg-1) were investigated. Different remediation methods with chemical oxidants were compared: KMnO4 0.10 mol L-1; K2S2O8 0.10 mol L-1; H2O2 0.10 mol L-1; H2O2/Fe2+ 0.10/0.08 mol L-1 (Fenton’s reaction) and H2O2/Fe2+/UV 0.10/0.08 mol L 1 (photo-Fenton reaction). The remediation was practically complete (99 %) after 30 min of the photo-Fenton process. No other oxidant reached this dissipation rate after 180 min. The remediation was least […]
