Abstract
This research paper concentrates on the efficiency of electrokinetic remediation of copper contaminated sand employing different electrode material, number and spacing. By optimising the selection of suitable electrode materials, coupled with the application of the appropriate number of electrodes and electrode spacing, it is expected that the remediation time will be drastically reduced. In addition, the methodology being investigated in this study will reduce inefficiencies in electrical field distribution. The effect of various electrode materials such as silver and graphite, and the influence of changes in the number and the layout of the electrodes on the overall remediation efficiency and time was investigated and evaluated. Experiments with one, two and three one-dimensional anode system have proved that remediation efficiencies as high as 91% can be attained.
