Phytoremediation belongs to relatively modern and frequently used methods of possible treatment of environmental problems (mainly caused by human activities). It consists in mitigating pollutant concentrations in contaminated soils with plants, which are able to accumulate or eliminate metals and various other contaminants. Nevertheless, the fundamental principles of this technique, i.e., transport of pollutants from soils into the plant cells have not been elucidated. These processes can be studied using model solutions of cadmium, lead and oxalic acid and the conditions in the rhizosphere can be studied within the artificially prepared phospholipid bilayer membrane on polycarbonate support. Electrochemical impedance spectroscopy (EIS) is used to monitor the formation and stability of phospholipid membrane, whereas voltammetric methods can detect species, which are transferred across the membrane.
