Abstract
In many areas in the world, the soil has been seriously contaminated, due practical of inadequate disposal and pollutant industrial activities. This contaminated soil becomes a threat to the environment for presenting toxical substances, as the heavy metals. It is important to consider that metals, besides causing damages to the environment, also offer serious risks to the human health. New techniques are being developed in the attempt to extract these contaminants from the soil, being one of them the technique of electrokinetic remediation, which has been considered promising because it presents an excellent potential of recovery of places contaminated by heavy metals. The objective of this work was to apply experimental design in the removal of copper ions from soil by electrokinetic remediation. The reactor performance was evaluated by the following variables: potential e time of remediation. Since there are almost no mathematical models fitting to the system and due to their complexity, it was decided to use a statistical technique, the full factorial design, for the attainment of the desired responses as empirical functions. This study has shown that statistical design can be applied for the removal of heavy metals ions, and it is an economical way of obtainig the maximum amount of information with the fewest number of experiments.
