The invention relates to a method for removing inorganic compounds from a section of soil. By regulating an electric voltage applied between two or more electrodes (1, 2) disposed in the section of soil (3) to values equal or below the electrokinetic point (61), inorganic compounds are electrochemically modified in situ in such a manner that they are electrokinetically mobilized and can be directly deposited on the electrodes (1, 2). According to the invention, the electrokinetic point (61) is adjusted and reached by applying a voltage to the electrodes (1, 2) and controlling it, once, after passing a first current/voltage zone (62) of a first gradient, a second current/voltage zone (63) of a second gradient that is smaller than the first gradient is reached.
Process for the removal of inorganic compounds from a ground area characterized by the that in situ by regulation of an electrical voltage applied between two or more electrodes (1, 2) installed in the ground area (3) to values at or below the electrokinetic point (61) inorganic compounds are changed so that they can be electrokinetically mobilized and deposited directly on the electrodes (1, 2), where the electrokinetic point (61) is set and reached by application and control of a voltage at the electrodes (1, 2) if after running through a first current/voltage range (62) of a first increase, a second current/voltage range (63) of a second increase, which is smaller than the first increase, is reached.
