Research Abstract

In Application of electrokinetic soil remediation to the heavy metals contaminated soils, the acidification might cause dissolution of part of the solid matrix, and so it is desirable to perform the soil treatment at neutral pH. However, the solubility of most heavy metals is significantly reduced at elevated pH values. The solubility of metals can be enhanced by adding reagents that form metal complexes. Apart from efficacy as metal extractants, complexing agents need also to be rated for safety of use. Biodegradability is of importance because treated soils always contain residual agents that may, upon soil reuse in the field, result in actual metal mobilization and transport to groundwater. It appears therefore essential for these residual agents to be rapidly biodegraded. This is even more important for in-situ soil flushing operations. In this research, the basic system of environmentally friendly in-situ electrokinetic remediation of heavy metals contaminated soils was proposed by using biodegradable chelating agents and biosurfactants.
