This paper presents results to assess electrochemical treatment as an option for the remediation of total petroleum hydrocarbons (TPHs) from contaminated soils. The electrochemical method was applied in an experimental setup with the next dimensions: 450 mm x 150 mm x 150 mm. The setup length was devised in three electrochemical cells that were connected at two power supplies. The power supplies configuration was provided in such a manner that each cell has a cathode and an anode without overlapping. The initial value of TPH concentration in soil was of 1420.28 mg/kg dry weight. Twenty-one days of application resulted in removal efficiency of 31%, with better results in the anode area respect to the cathode one (33% respect to 27%). The energy consumption registered after the development of the experiment was 10.6 kWh for exterior power supply and 16.1 kWh for the interior one. https://waset.org/publications/10007754/removal-of-total-petroleum-hydrocarbons-from-contaminated-soils-by-electrochemical-method.
