Abstract Diesel‐contaminated soil was treated with Fenton's oxidant, from hydrogen peroxide. Soil samples were collected during the earthmoving of RNEST Oil Refinery (Petrobras). A factorial design 3 evidenced that concentration iron ions [Fe 2+ ] variable most statistically significant effect in all experiments. The oxidation efficiency found to be 57 % total organic carbon (TOC) and 78 polycyclic aromatic hydrocarbon (PAH) removal. Moreover, sum low‐molecular‐weight PAHs on high‐molecular‐weight determined. remediation a pilot‐scale reactor led reduction nearly 80 PAHs.
