Polynuclear aromatic hydrocarbon (PAH) release from soil during treatment with Fenton's reagent

Degradation of polycyclic aromatic hydrocarbons (PAHs) in contaminated soils by Fenton's reagent: A multivariate evaluation of the importance of soil characteristics and PAH properties

“…In fact, benzo(a)pyrene and perylene were more efficiently removed than some PAHs with considerably lower log K ow values. Further, although phenanthrene and anthracene are structurally similar and possess similar log K ow values anthracene was degraded to a greater extent (37%) than phenanthrene (23%) [43,46], which might be explained by the fact that anthracene possesses a linear configuration (as opposed to phenanthrenes angular configuration) and higher ionisation potential (and higher reactivity towards hydroxyl radicals) [45]. Finally, acenaphthene, which combines the lowest log K ow value (Fig.…”

Determination of potassium permanganate demand variation with depth for oxidation–remediation of soils from a PAHs-contaminated coking plant

“…The elevation of concentration may be due to the changes of properties and concentrations of soil organic substances during oxidation, consequently desorption of PAHs was enhanced [19]. Kawahara et al [20] and Yan and Sun [21] found that oxidation could reduce the concentrations of organic substances in soil, particularly humic acid, which considerably influenced the adsorption behavior of PAHs and decreased their partition coefficients in the soil.…”

The Fate of Hydrogen Peroxide as an Oxygen Source for Bioremediation Activities within Saturated Aquifer Systems

“…Several sources of naturally occurring Fe species capable of mediating these reactions that can be attributed to H 2 O 2 degradation have been detailed in the literature. 46,47,48 Candidate species reported include simple ferrous iron (Fe 2+ ), geothite (a-FeOOH), and ferrous sulfates (e.g., FeSO 4 ). Soils typically serve as a good reservoir of Fe compounds, as discussed by Dragun and Chiasson.…”
