PETROL HİDROKARBONLARI İLE KİRLENMİŞ DOĞAL TOPRAĞIN ELEKTROKİNETİK YÖNTEMLE ARITIMI

treatment of natural soil contaminated with petroleum hydrocarbons, in laboratory scale reactors. Electokinetic remediation of agricultural soil with an initial TPHs concentration of 10000 ppm was investigated under 20 V or 40 V electrical potential by using distilled water as electrolyte solution, treatment efficiencies between 55.2 and 95.6 % were observed according to the distance from the anode chamber and the applied electrical potential. The effect level of electrokinetic remediation on 16 polycyclic aromatic hydrocarbons (PAHs), which were announced by EPA as in high toxicity group and present in engine oil that was used as contaminant, was also included in the framework of the study. Similar with the findings with TPHs, it was observed that PAHs treatment efficiencies were between 73.9 and 87.8% according to the distance from the anode and the electrical potential applied to the system

TREATMENT OF PETROLEUM HYDROCRBONS CONTAMINATED NATURAL SOIL BY ELECTROKINETIC METHOD

Remediation studies were conducted to determine the effectiveness of electrokinetic method on the treatment of natural soil contaminated with petroleum hydrocarbons, in laboratory scale reactors. Electokinetic remediation of agricultural soil with an initial TPHs concentration of 10000 ppm was investigated under 20 V or 40 V electrical potential by using distilled water as electrolyte solution, treatment efficiencies between 55.2 and 95.6 % were observed according to the distance from the anode chamber and the applied electrical potential. The effect level of electrokinetic remediation on 16 polycyclic aromatic hydrocarbons (PAHs), which were announced by EPA as in high toxicity group and present in engine oil that was used as contaminant, was also included in the framework of the study. Similar with the findings with TPHs, it was observed that PAHs treatment efficiencies were between 73.9 and 87.8% according to the distance from the anode and the electrical potential applied to the system
