Project
Summary:
The feasibility of a new in-situ remediation technique was tested. The remediation technique makes use of the principles of electro remediation, combined with the use of iodic complexants to solubilize the mercury from the soil, and solvent extraction to isolate the recovered mercury from the waste solutions. The complexants are introduced into the soil by means of an electric field (electroremediation). This field is also used to remove the solubilized (ionic) mercury complexes from the soil. Soil electrodes are flushed with process solution, which is treated above the ground to isolate the mercury and to reuse the iodic complexes.

Achieved Objectives:
The objectives of phase 1, 2 and 3 were achieved. The project was stopped during the execution of phase 4/5. It became clear that the technique could never be economical feasible, because of the introduction of some needed extra process steps.
