英文摘要	Salt-affected soils are found mainly in arid and semiarid regions. In these areas, weak precipitation rate causes salt accumulation at high level on the soil surfaces, leading to drastic modifications in soil properties, affecting hence the environment, human health and civil engineering infrastructure and facilities. This research aimed to study the performance of the electrochemical treatment on removal of hazardous cationic salt including sodium, potassium and magnesium cations. The novelty of this work lies in the investigation of the potential of electroosmosis phenomenon as a driving vector in the removal of cationic hazardous salt during its regularized path toward the cathodic area. Therefore, a controlled-permanent analysis of contaminated catholyte water over processing time was achieved, in order to understand the evolution of contaminant removal during treatment time via the electroosmosis process. For this purpose, five relevant indices were evaluated, including electric current, electroosmotic flow, pH, electrical conductivity and cationic hazardous salt removal efficiency. Experimental tests were conducted in laboratory-designed cell using different electric potential difference for a total period of 8 days. Owing to the electroosmosis phenomenon, salt contaminants migrated and accumulated in the catholyte chamber, facilitating thereby their removal. Among these contaminants, sodium and potassium exhibit the highest decontamination efficiency with a rate of 88 and 85%, respectively. Magnesium ions show moderate removal with a percentage of 53%, due to the pH gradient, degree of hydration, ionic valence and mobility. The results demonstrate that the electrochemical treatment may be an efficient method for remediation of saline low-permeable heterogeneous soils.
