THEORETICAL ASPECTS OF THE ELECTROKINETIC METHOD OF REMOVING RADIONUCLIDES FROM THE SOIL

A theoretical model is developed for the electrokinetic method of remo ving contaminants, in particular, immobilized radionuclides, from the soil. The method involves applying a constant electrical held to the s oil. The field ensures the electromigration supply of a complexing age nt into the soil and removal of the pollutant-containing complexes. Po ssible modes of the soil purification process are analyzed. The soil p urification process is shown to depend essentially on the ratio betwee n the rates of the complexing reaction and the transport processes.
