Combination of Electrokinetics and nZVI Remediation

Popis výsledku v původním jazyce

Electrogeochemical processes as a whole remedial technology have a considerable application potential. They may be applied at sites with complex geological conditions where hydraulic intervention is inefficient or unreliable. In the case of ClE remediation, electrochemical processes can substantially accelerate not only the time necessary for the process of reductive dechlorination, but they also significantly reduce the necessary dose of principal reagents-especially costly nanoscale zero-valent iron (nZVI) particles. It is of operational importance to accelerate the transport of nZVI and its oxidation products in the electric field and to ensure the homogeneous distribution of nZVI in the required space by suppressing the aggregation of the particles. By arranging the electrodes, it is possible to accelerate the migration or, in contrast, stabilize the particles at a predetermined location. For example, this effect can be used to operate geochemical reactive barriers that can reliably replace hydraulic barriers at certain sites. At the model site, a decrease in the measured concentrations of ClE in relation to the connection of a direct current is demonstrated. These concentrations were measured in the monitoring boreholes that were not directly used to infiltrate the reactants and are located between the electrodes. This demonstrates a spatial reduction in the concentrations throughout the treated area.
