Abstract

The electrokinetic method for the remediation of contaminated aquifers is realized by applying a fixed low voltage direct current between anode and cathode which are set into the contaminated zone. The electric current and electric potential between anode and cathode is the important operational variables for the electrokinetic re- mediation. However, the variations of these variables have not been cleared, be- cause this method is relatively new and is an inovative technique. Depending on the time variation of the electric curret, the removal process can be divided into the first stage and the secon
