Resumen:
The effects of the electro - kinetic treatment in presence of surfactant Triton X - 114 on the physical and chemical properties of Gleysol soil were investigated. With the characterization of polluted Gleysol soil, the results showed the highest concentration of greases and oils related with hydrocarbon content in the fraction of soil between 50 and 100 mu m, which is the smallest group of particle size with 4 452 mg kg(-1) of light and medium petroleum fraction. This sand fraction of polluted soil showed a decrease of real density with an increase of organic matter content, because they have low densities than saturated fractions and are more easily oxidized by the Walkley - Black method. However, the electric conductivity and the cation exchange capacity did not have any effect with the presence of the pollutant, because by scanning electron microscopy was observed the heterogeneous hydrocarbon distribution and the presence of laminate structures in some areas. This effect was evalua
