A Review on Soil Remediation by Fenton Process

As the development and population of a country grow, its industrialization and other modern techniques also increase to meet the growing demand of the people. These technologies, as progress, directly and indirectly, are affecting our environment in many ways. These effects include the vitiating the ambient air quality due to the emission of the harmful gases from various industrial and human activities; water is being polluted by so many toxic matters and contamination of the soil by various degradable and non-degradable matter is also becoming very common. The contaminated soil may have so many adverse effects on our environment like polluting the groundwater, harmful for vegetation, other lives, etc. However, many methods are being adopted by researchers and engineers for the making such soil free of contamination but among all methods of treatment advanced oxidation process(AOP) is one of a favorable method for the soil that is contaminated with highly and non-easily removing pollutants. There are many methods of AOP itself that are used for this purpose like photocatalysis (TiO₂), Fenton processes, ozonation and plasma oxidation, etc. that have their characteristics and effectiveness. The present study only focuses on the Fenton process and its mechanism for the treatment of the soil. Also, this paper reviews the performance of modified Fenton processes for removal of highly stabilize pollutants from the soil.
