description: Soil contamination with oil-processing products is quite frequent. The remediation of such soils with biodegradation, soil air venting (or steamy stripping), etc, is quite complicated and usually not cost-effective. Advanced oxidation processes (AOP) have been used mainly for degradation of bioresistant compounds in aqueous medium. Some recent studies have demonstrated the efficiency of AOPs for contaminated soil remediation as well. Implementation of oxidation technologies has a target to transform difficult biodegradable components into better biodegradable ones. The present study aims to achieve basic data in order to enlarge the application area for AOP on the remediation of soil contaminated with oil-processing products.

The main goals are:
? to study the degradation of the main groups of organic compounds present in the soil contaminated with oil-processing products (aliphatic, cyclic, aromatic, etc.) in order to find the most effective AOP for their degradation;
? ascertain the suitability of different AOPs (Fenton treatment; Fenton like processes; ozonation and/or H2O2 and their combinations with UV- and solar radiation) for degradation of pollutants in soil contaminated with different kind of oil-processing products (petrol, gas-oil (diesel oil), shale oil, etc) and their ability to improve consequent biodegradation;
? to study the reaction intermediates formed during the advanced oxidation treatment as a key to the efficiency of various treatment processes and steps;
? to study the influence of the chemical composition and the humidity of soil on the remediation efficiency.
The study will result in elaborating basis of the technology utilising advanced oxidation for in situ soil remediation.
