Impact of activated sodium persulfate with different activators on petroleum hydrocarbon-contaminated soil
This study presents in-situ chemical oxidation remediation of petroleum hydrocarbon-contaminated soil using non-activated Sodium Persulfate (SP), Zero-Valent Iron (ZVI)-activated SP, and cement-activated SP. All experiments were performed at the soil's optimum moisture content of 14 % to mainta...

| description | This study presents in-situ chemical oxidation remediation of petroleum hydrocarbon-contaminated soil using non-activated Sodium Persulfate (SP), Zero-Valent Iron (ZVI)-activated SP, and cement-activated SP. All experiments were performed at the soil's optimum moisture content of 14 % to maintain the physical integrity for its potential reuse in construction applications. Test results showed that the addition of 5 % SP reduces Total Petroleum Hydrocarbons (TPH) by 61.7 % and 70.2 % after 7 and 28 days, respectively. Activating SP with ZVI at the optimal dosage of 0.5 % successfully accelerates remediation, achieving in just 7 days the same level of hydrocarbon decontamination that occurs at 28 days using SP alone. Cement-based activation exhibits lower TPH degradation, with a maximum reduction of 33.1 %. In addition, the results showed that aromatic hydrocarbon compounds were preferentially oxidized over aliphatic compounds. Overall, these findings establish ZVI-activated SP as an effective and rapid approach for the remediation of TPH-contaminated soils. |
