This work studied the structural effects of hematite (α-FeO), 2-line ferrihydrite (HFO) and goethite (α-FeOOH) on diethyl phthalate ester (DEP) degradation. The results showed that the degradation of DEP was faster under 365 nm light irradiation than in the dark in the presence of iron (hydr)oxides. The apparent kinetic rates of DEP degradation followed the order HFO > goethite ≈ hematite in the dark and HFO > hematite > goethite under 365 nm light irradiation.
