The degradability of total petroleum hydrocarbons (TPH)‐contaminated soils by hemoglobin‐catalyzed oxidation with hydrogen peroxide (H 2 O 2 ) was investigated using 8 g H 2 O 2 kg −1 soil and 3.3 g hemoglobin kg −1 soil. When both hemoglobin and H 2 O 2 were used to initiate the oxidation reaction, approximately 76% TPH removal was achieved, while only 26% was removed when only H 2 O 2 was used. This shows that the TPH removal can be enhanced in the presence of hemoglobin as a catalyst. In addition, the toxic effect of the soil treated by the hemoglobin‐catalyzed oxidation, determined using Microtox®, was reduced by about three times compared to the untreated soil. Overall, this study shows that hemoglobin may successfully act as a catalyst enhancing TPH removal in soils.
