Abstract
Novel soil remediation equipment based on electro-kinetic geosynthetics (EKG) was
developed for in situ isolation of metals from paddy soil. Two mutually independent field plot
experiments A and B (with and without electric current applied) were conducted. After saturation using
ferric chloride (FeCl3) and calcium chloride (CaCl2), soil water drainage capacity, soil cadmium (Cd)
removal performance, energy consumption as well as soil residual of iron (Fe) and chloride (Cl) were
assessed. Cadmium dissolved in the soil matrix, and resulted in a 100% increase of diethylenetriaminepentaacetic
acid (DTPA) extracted phyto-available Cd.
