In the present era, environmental pollution is a global crisis, increasing population growth and urban development, industrial expansion and unlimited use of natural resources, are among the increasingly important factors of pollutants (Reilley, 1996). Vocciante (2021) found in the study of stability in electrokinetic modification processes that the electrokinetic method is suitable for cleaning inorganic pollutants from clay. Zhou (2021) found that using the electrokinetic method is effective in removing heavy metals zinc, cadmium, and manganese from the soil and leads to the removal of about 72% of the pollutant from the soil sample. Vaishnavi (2021) in the study of bio-electrokinetic modification of diesel-contaminated environment with biosurfactant found that this method is an effective method for cleaning and cleaning soils contaminated with diesel hydrocarbons. Hanaei et al. (2021) found that the direct shear test showed that the adhesion of the soil sample increased and the friction angle decreased after oil contamination, and the permeability test showed that the contamination of the soil sample decreased the permeability of sandy soil and this change It is a function of the amount of oil and the viscosity of oils.

Pollution of soils containing petroleum products is one of the most important environmental challenges. Therefore, it is necessary to take measures for the purification of petroleum products, including diesel, to clean these compounds from the soil, various solutions are used, including the use of electrokinetic process. The result of the electrokinetic process in the soil is the movement of water, ions and charged particles due to the difference in electrical potential. In this study, the purification of diesel-contaminated clay by electrokinetic method in the presence of ABTS and saponin surfactants is investigated and the effect of pH control on catolite and anolite on the electrokinetic modification process of clay is evaluated, The results show that in the absence of the surfactant, the electrokinetic method has a very low removal efficiency of 3% to 7%, but in the presence of the surfactant, the efficiency is significantly increased by 20% to 54%, with pH control in Velit. and anolyte and the amount of active substance increase the level of efficiency of diesel removal from soil. With the use of Saponin, the lowest amount of removal at a concentration of 0.05% equal to 20% has been obtained, while ABTS has been able to remove about 54% of diesel at the highest concentration of surfactant (0.15%), in the continuation of the research A uniaxial test has been conducted to determine the unconfined compressive strength of the soil sample, which shows that the cleaning process increases the compressive strength of the soil by 15%.
