Graphite-stimulated electrodialytic remediation

Start date: Nov 1st, 2018
Finish date: --

Soil samples collected from Collstrup are used in a lab-scaled electrodialytic remediation (EDR) experiment. The purpose of this experiment is to remove heavy metals (Cu, Cr, As) from the contaminated soil by a new EDR system. This new EDR is developed by adding graphite particles into soil repair chamber between two main electrodes. Those added graphite particles will be polarized and act like micro electrodes during EDR process, which is believed to be helpful in improving mass transfer. It is expected to be more efficient than conventional EDR process in remediating this soil and reducing its potential hazard to the environment.

The experiments are conducted by DTU Civil Engineering
