| 摘要 |
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.
