Remediação eletrocinética integrada a Fenton para o tratamento de solo de solo contaminado com petróleo: estudo em solo de baixa permeabilidade

Abstract

In recent years, soil contamination has been a cause of concern for both society and researchers in particular, a useful contamination of hydrocarbons and their derivatives. In this case, contamination is often associated with fossil fuels (gasoline, diesel or aviation fuel, etc.). The environmental impact caused by these pollutants is due to their hydrophobic characteristics. Oil, which is not a major raw material of these contaminants, can be represented as total petroleum hydrocarbon (HTP). HTPs represent a broad family of compounds whose function is determined according to the carbon equivalent number, such as gasoline and diesel using groups (C6 to C10-12) and diesel (C8-12 to C24-26), respectively. Currently, seeking treatment technologies that minimize the damage caused by these compounds, electronic remediation (RE) has been used to treat soils contaminated with organic and organic compounds, whereby contaminants can be moved to controlled extraction points. In this context, this work aims to investigate or couple the RE-Fenton process to eliminate hydrocarbons in low permeability soils. Database scale RE-Fenton experiments were used using a kaolin. RE-Fenton experiments were used iron electrodes, investigating different electrolytes, applying a potential of 1 V / cm for 15 days. The proven results that coupling RE with Fenton allowed for greater removal of compounds caused by hydrocarbon oxidation.
