ELECTROKINETIC REMEDIATION OF FLUORINE-CONTAMINATED SOIL

A method for purifying soil polluted with fluorine is provided to remove effectively the fluorine contained in the soil, by selecting an electrolyte for eluting the fluorine and using the relation between concentration of the electrolyte and current density of kinetic electricity. A current supply unit is prepared. An anode tank and a cathode tank are distanced from soil polluted with fluorine, wherein the soil is disposed between the anode tank and the cathode tank. An alkaline solution is inputted into the anode tank, which is connected to the current supply unit, using a circulation pump. An alkaline solution is inputted into the soil to elute fluorine while electric current is passed through the soil, thereby removing the eluted fluorine in the anode tank and the cathode tank by electro-migration and electrical osmosis.
