| Zusammenfassung |
| The main objective of this work is the use of soil flushing technology to the treatment of contaminated soils by Zn2+ and Cu2+. Soil flushing is characterised by the metal extraction from soil by aqueous solutions and the subsequent extracted solution treatment. For this reason, four different soils were artificially contaminated by Zn2+ and Cu2+. Then, soils were treated by solutions with different extracting agents at different times. Experimental results have shown that extraction percentage of metals significantly depends on kind of metal, extracting agent and soil properties such as cation exchange capacity, pH, organic matter content or clay content.
