摘要: AbstractVanadium, a hazardous pollutant, has been frequently detected in soil and groundwater, however, its transport behavior porous media were not clearly understood. In this study, the effects of solution pH, ionic strength (IS) effect clay mineral on vanadium saturated investigated. Laboratory experiments using series columns packed with quartz sand carried out to explore retention range ionic-strength (0.001–0.1 M) pH (4–8) two different types minerals montmorillonite kaolinite. Results breakthrough showed that was highly mobile media. The increase rendered higher study also indicated an easier transfer IS. Montmorillonite enhanced mobility column when compared A mathematical model based advection-d...
