A pilot-scale electrokinetic (EK) separation field test (2×3×0.2 m3, W×L×D) was performed in a greenhouse to remove salts from saline soil. Initially, the greenhouse soil had high electrical conductivity (EC), about 9 dS/m, and contained mainly Ca2+, Cl- and SO42- ions. After 2 weeks of EK treatment, the soil EC was reduced to 52% compared with its initial value. The EC reduction was mostly achieved within the first week (47%) due to removal of Na+ and Cl- ions, but ions with a high adsorption capacity such as Ca2+ and SO42- ions were difficult to be removed. During the EK test, the soil temperature increased and it reached around 50 ℃ at some regions. For in situ application to soils in cultivation, the current should be controlled to limit increases in temperature, especially near the cathodes. In conclusion, the in situ EK technique is feasible for the restoration of saline greenhouse soils in or no cultivation and an appropriate strategy is necessary for more effective remediation.
