Surveying the effect of electrokinetic together with leaching remediation on quality of drain water of a saline-alkaline soil

The salinity of water and soil is called white death in many countries, because of its importance. Generally, the quantity of leaching water, energy consumption and time usage of soil remediation procedure are important factors which affect suitable method of soil reclamation. Electrokinetic (EK) is a physical method for salt extraction such as chemical, Organic and inorganic compounds. In this study, the horizontal placement of electrodes along with leaching procedure was used in Electrokinetic remediation of a saline-alkaline soil. For this purpose, two aluminum and reticular electrodes was placed above and under the soil column as anode and cathode, respectively. The soil columns heights were 10, 20, 30 and 45 cm. Then leaching water (30 mm) every day and totally Equivalent to Four times pore water was entered to soil and properties of drain water was measured. Although, leaching procedure without applying electrokinetic technique was done as control treatment. The results showed that Electrical Conductivity (EC) of drain water and current rate was changed sinusoidal in EK. Although, PH and temperature of drain water was changed between 6.8 to 9 and 23 to 35 centigrade, respectively. Leaching of cations increased in EK technique significantly (p
