Fenton chemistry encompasses reactions of hydrogen peroxide in the presence of iron to generate highly reactive species such as the hydroxyl radical and possibly others. In this review, the complex mechanisms of Fenton and Fenton-like reactions and the important factors influencing these reactions, from both a fundamental and practical perspective, in applications to water and soil treatment, are discussed. The review covers modified versions including the photoassisted Fenton reaction, use of chelated iron, electro-Fenton reactions, and Fenton reactions using heterogeneous catalysts. Sections are devoted to nonclassical pathways, by-products, kinetics and process modeling, experimental design methodology, soil and aquifer treatment, use of Fenton in combination with other advanced oxidation processes or biodegradation, economic comparison with other advanced oxidation processes, and case studies.

The ozonation and the Fenton treatment of soil spiked with a mixture of eleven polycyclic aromatic hydrocarbons (PAH) were studied. The efficiency of the treatment was strongly dependent on the matrix of soil (sand or peat). PAH adsorbed on sand undergo degradation more easily and require less oxidants (ozone, hydrogen peroxide) than PAH adsorbed on peat. Soil ozonation and the Fenton treatment were effective not only for the removal of 3‐ring PAH, but could effectively degrade also 4‐, 5‐ and more ring PAH. PAH removal from soil with the Fenton treatment in slurry was found to be dependent on the ratio of H2O2/soil/Fe2‐, the manner of addition of hydrogen peroxide, and the treatment time. Three‐phase ozonation of PAH contaminated soil resulted in a lower PAH removal and required higher ozone doses than two‐phase ozonation. An improvement of the biodegradability during the chemical oxidation favours the implementation of combined chemical treatment and biodegradation for remediation of PAH contam...
