“…The results were consistent with the findings reported by other authors (Ferrarese et al, 2008). According to Yen et al (2011Yen et al ( ), 2011, total removal efficiencies of petroleum hydrocarboncontaminated soil with the three oxidants followed the order of permanganate > persulfate > hydrogen peroxide. Besides, PAHs are regarded as the most recalcitrant organic compounds, and their long-term existence in sediment makes degradation process unlikely to happen; therefore, in order to enhance PAH removal efficiency, more powerful oxidation conditions to provide stronger oxidizing species (SO 4…”

, and temperature (50-70°C) were performed. The efficiency to remove PAHs was 10.7-39.1% for unactivated persulfate. The treated sample had over 50% of the persulfate still remaining from an initial persulfate dose of 170 g/L, whereas less than 1% of the persulfate remained from an initial persulfate dose of 0.017, 0.17, and 1.7 g/L. Adequate persulfate (170 g/L) must be present because it is the source of the sulfate radicals responsible for the degradation of PAHs. Results indicated that increasing temperature and the addition of nZVI into a persulfate-slurry system could enhance the persulfate oxidation process. The best removal efficiency (90%) was achieved after 24 hr while adding nZVI (0.01 g/L) to persulfate (170 g/L) at temperature of 70°C. The results suggested that nZVI assisted persulfate oxidation without elevating temperature may be a suitable and economic alternative for the ex situ treatment of PAH-contaminated sediments.Implications: Nano zero-valent iron (nZVI) has been successfully applied to transform/degrade contaminants in soils and water. Additionally, nZVI has been used as a catalyst to activate persulfate for the treatment of various contaminants. In this study, with the support of temperature, nZVI-persulfate oxidation system for treatment of PAH-contaminated sediments was improved significantly and the treated sediment could meet remediation goals.

“…Thus, the concentration of PS/Fe 2+ molar ratio should be controlled to decrease the adverse effects of ferrous ions on sulfate radical production (Figure 2). Equation (3) shows the scavenging effects between sulfate radical and ferrous ion (Yen et al 2011).…”

Soil & Water Res., 11: 131-138.In this study, batch system experiments were carried out for evaluating the capability of persulfate (PS) to remediate fuel oil contaminated soils. Remediation was performed by spiking soil samples with fuel oil and then treating the mixture with sodium PS. Different controlling factors including pH (3, 6, and 9), PS concentrations (50-500 mmol/l), metal activators (ferrous sulfate, magnetite, and MnO 2 ), and temperature (25, 40, and 60°C) were considered. Results proved that PS oxidation is effective in fuel oil degradation. The best PS : Fe 2+ molar ratios were reported 400 : 2 and 250 : 1 for silty clay and loamy sand soil samples, respectively. Lower pH was more of interest in removal of fuel oil by PS oxidation. MnO 2 improved fuel oil degradation when used together with metal activators. The results showed that when MnO 2 was used together with ferrous sulfate and magnetite at acidic condition (pH = 3), the removal efficiencies were the best. Increasing temperature from 25 to 60°C improved the fuel oil degradation in the PS oxidation batch system. The results showed that activating PS by using ferrous sulfate along with MnO 2 at acidic condition in 60°C could increase fuel oil degradation near to 58% in silty clay soil samples, while the degradation rate for loamy sand soil samples in similar conditions was 62%.

“…In situ chemical oxidation (ISCO) has gained increasing attention in recent years because of its effectivity on remediating toxic chemicals contaminated soil or ground water [1,2]. The four main oxidants used in ISCO are permanganate, hydrogen peroxide (HP), persulfate (PS) and calcium peroxide (CP) [3][4][5][6].…”
