Basic principles and problems in decontamination of natural disperse systems. The electrokinetic treatment of soils.

The main chemical, biological and physical methods of deactivation of such natural disperse systems as soils and bottom sediments from charged and uncharged pollutants are analyzed. The impact of properties of natural disperse systems and the substances causing their contamination on the expediency of using some specific detoxication method is considered. The peculiarities of ex-situ and in-situ treatment are indicated.
